Here’s how you can spot a fake ATmega328P – a commonly counterfeited microcontroller, especially in Arduino-compatible boards: 1. Visual Inspection (ATmega328P) Markings: Genuine chips have clean, crisp laser markings or printing. Fakes may show blurry text, incorrect fonts, or an outdated/fake Atmel or Microchip logo. Suspicious Date Codes: For example, a chip marked with a 2024 date under the Atmel brand is suspicious, since Microchip acquired Atmel in 2016. Package Anomalies: Surface may show sanding or grinding (to re-label an old chip). Unusual finish (too shiny, too matte, or inconsistent with genuine chips). 2. Functional Testing Bootloader Issues: Bootloader flashing may fail. Programming via Arduino IDE may be unreliable or only work at 8 MHz (instead of 16 MHz). Unstable Behavior: EEPROM errors. Resets or crashes when power-cycled. Signature Mismatch: Use avrdude or similar tools to read the chip signature. bash avrdude -c usbasp -p m328p Expected signature: java Device signature = 0x1e950f Fake chips may return incorrect or inconsistent signature bytes. 3. ISP Programming Problems May have incorrect fuse bits. Could refuse to lock/unlock properly. Show strange behavior on SPI or other low-level protocols. 4. Electrical Behavior Higher-than-expected power consumption. Overheating even when idle. Unstable at lower voltages (e.g., under 5 V). 5. Supply Chain Checks Authorized distributors: Digi-Key, Mouser, Farnell, Arrow, Ampheo, etc. Trusted Arduino-certified vendors for official boards. Avoid: eBay, AliExpress, or other marketplace sellers offering very low prices or "bulk chips" with no traceability. 6. Community Knowledge Relabeled chips (e.g., ATmega8 or ATmega48 being sold as ATmega328P). Chips requiring modified bootloaders to work at all. You can check: EEVblog Forums Reddit /r/arduino Arduino forums for part number and batch discussions.  ( 3 min )

Linkerd automatically enables mTLS for all TCP traffic between meshed pods. To do so, it relies on several certificates that must be in place for the control plane to function correctly. You can supply these certificates during installation or generate them with third-party tools such as cert-manager or trust-manager. The required certificates are the Root Trust Anchor and an Identity Intermediate Issuer Certificate, which work together to issue a unique Leaf Certificate for every meshed workload. Linkerd’s Root Trust Anchor is a public CA certificate that serves as the ultimate trust point for all service-mesh certificates. It never issues workload certificates directly; instead, it signs intermediate CA certificates, which then issue the workload certificates. This separation lets each …  ( 6 min )

On Android devices, particularly those preloaded with Google services, you may notice a system app called Google Partner Setup running silently in the background. While it doesn't have a user interface or appear in your app drawer, it plays a crucial role in ensuring your device and certain apps function smoothly. But what exactly is it, and why is it running behind the scenes? Google Partner Setup is a pre-installed Android system component responsible for coordinating specific functions between the Android operating system and apps that rely on Google’s core services. It primarily helps manufacturers (like Samsung, Xiaomi, or Motorola) integrate their custom Android skins and features with Google's ecosystem, ensuring consistency, compliance, and usability. Google Partner Setup operates in the background because it supports critical functions that don't require user interaction. Here’s why this background process is necessary: 1. Syncing Device Features with Google Services 2. Enabling Device-Specific Customizations 3. Supporting App Compatibility 4. System Configuration at Boot 5. Ongoing Performance Adjustments Yes, Google Partner Setup is safe and necessary for most Android devices that rely on Google's core apps and features. It’s not spyware or bloatware, and removing or disabling it may disrupt system performance or cause sync issues with your Google account. While it is technically possible to disable Google Partner Setup using developer tools or ADB commands, it is not recommended. Disabling it can result in: Failure to sync contacts, calendar, or other Google services Google apps not functioning correctly Issues with system updates or manufacturer-integrated features Google Partner Setup runs in the background to ensure stable integration between Android, the device manufacturer’s features, and Google’s services. It may seem invisible to the average user, but its background activity is essential for a smooth and consistent Android experience.  ( 4 min )

Created by: Google First announced: July 2022, at CppNorth Status: Experimental / Pre-alpha As a wise old man had said. With great power comes great complexity. And that's how I define C++, it is also too hard. It's this hard that big companies had to jump in and stop it, and find an alternative or create an alternative. That's what Carbon was created for. The goals in the mind of Google were: Performance critical, like C++ Interoperability with existing C++ code Safe and modern syntax Fast compilation Tooling and ergonomics first Basically, Carbon wants to be modern but not restrictive. If you’ve written Rust, Kotlin, Go, or Swift, Carbon will feel very good at first sight. Vari…  ( 4 min )

A few weeks ago, I paid $3,000 for an AI mentorship program by Ritesh Verma. He runs a YouTube channel and a website called BecomeABotDeveloper, which promises to teach people how to build and sell AI agents. This is what the headline on the landing page said: “Make $5,000/month in 6 weeks building AI agents. Guaranteed income or your money back.” It sounded very convincing at the time. We had a video call, and I decided to join. The course mainly covered: Basic Puppeteer scripting for web scraping Some automation using n8n A bit of Reddit outreach strategy A short LinkedIn Sales Navigator video Mentions of tools like Apollo for cold emailing I found the technical content very basic — I’ve honestly seen better tutorials on YouTube for free. It felt more like a beginner-friendly automation overview, not an advanced mentorship on building or selling AI agents. Personally, the program did not meet my expectations. It was promoted as a business-building mentorship with a clear income promise, but what I got was surface-level automation content and vague outreach tips. There was a refund policy: if I stayed active for 4 weeks and didn’t get a project, I’d get my money back. I followed the rules, but received only a vague message about a “project” with no details. Eventually, after saying I might share my experience, I was refunded $1,200 — but I’m still down $1,800. If you’re reading this while researching Ritesh Verma or BecomeABotDeveloper, I hope this post gives you more context than just the marketing material.

Just recently saw this post and decided that it would be interesting to test out Amazon Q CLI capability by building a game, so here we go! First, I started by finding a game idea. Well turns out my high school teacher friend has some students find understanding physic concepts difficult, like free body diagrams. So I created this game for her students to understand the concepts easier~ With the game idea in place, I then proceed to setup the development environment and get my hands dirty. For anyone interested, you can refer this guide to install Amazon Q CLI. Basically Amazon Q CLI is like ChatGPT/Grok/DeepSeek but in the form of CLI, so it's quite easy to use as long as you are comfortable with CLI environment. So with Amazon Q CLI ready, now is time for prompting! It's working better than I expected as it appears Q is using a reasoning model by default, though the response time could be quite long as a trade-off. Therefore, after endless prompting and revising, i find the below tips that maybe usefull in facilitating effective prompting and reduce the back-and-forth between you and Q: Define a prompting framework such that the Q know the context, the task, and the expected results Ask Q to provide visual debugs can let the Q know how to fix issues more quickly Ask Q to give a plan before coding, that way you know Q is thinking as you expected With about 3 hours prompting and waiting, here's the final product! https://fbd.cmpapp.top GitHub: https://github.com/john-ng-hk/stem-fbd-game That's all and thanks for reading, feel free to connect me on LinkedIn too~  ( 3 min )

Microsoft Excel is more than just a spreadsheet application—it’s a foundational tool that transforms raw data into meaningful insights. From simple lists to complex data models, Excel provides a flexible environment for organizing, analyzing, and visualizing information across industries and disciplines. PivotTables: These allow me to summarize and analyze large datasets quickly. For example, I used a PivotTable to count product entries by rating category and discount level, helping me uncover patterns in pricing strategies. IF Function: The =IF () formula is incredibly useful for categorizing data. I applied it to group products into “Excellent,” “Average,” and “Poor” rating categories based on numeric thresholds, which made my dataset more meaningful. Data Sorting and Filtering: By combining Excel’s sorting tools with slicers, I was able to isolate top-performing products based on ratings, reviews, and discounts. This made it easier to create targeted visualizations and focus my analysis on what matters. Conditional Formatting: This feature highlights cells based on criteria, like coloring cells red for values below a threshold. It’s ideal for spotting outliers in financial data or tracking project deadlines. Learning Excel has completely reshaped how I view data. What once seemed like overwhelming numbers in rows and columns now feels like a story waiting to be uncovered. Excel has taught me that with the right tools, I can dig beneath the surface of data to find insights that are not only informative but transformative. It’s made me more curious, more confident, and more equipped to approach challenges—one cell at a time.  ( 4 min )

Hey devs! 👋 During a recent discussion with some colleagues about TypeScript decorators, we ended up deep-diving into Angular.dev and stumbled upon something interesting — the @Attribute decorator. Though it's not as commonly used as @Input, it's a powerful and underutilized feature in Angular. So, I wanted to take a moment to share what I learned about it, along with a real-world example. 🚀 @Attribute in Angular? The @Attribute decorator is a parameter decorator used in a directive's constructor to inject a host element's attribute value as a static string. It allows a class (typically a directive or component) to access a static HTML attribute value at construction time, even if it’s not bound to an Angular input. ✅ Great for static values from HTML attributes 🚫 Not reactive (doesn’…  ( 5 min )

When Databricks announced Lakebase, most people dismissed it as just another product. Even Databricks markets it as "the backend for AI Agents and Data Apps." This messaging puzzles me. It's the same pattern they followed with Delta Lake in 2019, positioning it as "bringing reliability to Big Data." But Delta Lake was actually much simpler: a transactional layer on top of an immutable object store. That's it. Yet this simple concept solved a massive architectural challenge—enabling storage and compute separation for data warehouses at scale. Storage and compute separation became the foundation for everything that followed: data sharing, unified storage formats, multiple query engines. But separation creates a problem: latency. For analytical workloads, this latency is manageable. For trans…  ( 4 min )

Welcome back to Journey Through Java! Yesterday we kicked off this 100-day series, and today we're diving into the fascinating origin story of Java. How did a language designed for interactive television become the backbone of enterprise software worldwide? Back in June 1991, Java wasn't even called Java. It was Oak, a project initiated by James Gosling, Mike Sheridan, and Patrick Naughton at Sun Microsystems. The original vision? Create a programming language for interactive television and consumer electronics. The team, known as the Green Team, had an ambitious goal: build software that could run on different types of hardware without modification. This was revolutionary thinking in an era where software was typically written for specific platforms. ![James Gosling, the creator of Java, …  ( 6 min )

The Hidden Power of Words in iOS Apps While developers obsess over animations and visual design, the most successful iOS apps share a secret weapon: exceptional UX writing. Apple's UX writing team has distilled years of experience into four transformative techniques that separate amateur apps from App Store champions. These aren't theoretical concepts—they're practical strategies that immediately impact user engagement, retention, and conversion rates. Most apps suffer from "essay syndrome"—filling space with meaningless descriptors that dilute the core message. Target These Common Culprits: Adverbs: "easily," "quickly," "simply" Adjectives: "fast," "simple," "great" Interjections: "oops," "hooray," "uh oh" Pleasantries: "sorry," "please," "thank you" Before: "Simply enter your license p…  ( 5 min )

That's the thing about real change: it doesn't always arrive with a bang. Sometimes it just rolls on in. Quietly. No parade. No keynote. Just this stubbornly little drift you only notice if you're looking. This is where we are now with financial services. There is no banner headline shouting "BREAKING: INDUSTRY TRANSFORMED." But beneath the jargon and panels, something is real in terms of how we conceptualize innovation. And yes, it's kind of a big deal. I’ve had a front-row seat to this slow-motion evolution. Between leading innovation efforts, trading notes with startups and regulators, and listening to enterprise leaders grapple with AI and agility over coffee (sometimes multiple coffees), I’ve realized: the biggest breakthroughs aren’t always technical. They’re philosophical. Cultural.…  ( 4 min )

I’ve been building most of my projects with React. I like my routing setup and know exactly how I want my apps to build and behave. However, one challenge kept bugging me: how to get faster page loads and better SEO for my React SPA — especially for blog pages — without having to switch to Next.js or rewrite my entire codebase. Many coworkers asked me why I don't use Next.js or other frameworks like Gatsby, but I wasn’t ready to change my entire architecture or routing logic (I will discuss real reasons in a future post). I wanted a solution that lets me keep writing React my way, but still get the SEO and performance benefits of static HTML files. Single Page Applications (SPAs) built with React usually serve a single index.html file and the client-side JavaScript handles routing. While …  ( 4 min )

As part of rewriting the documentation for my custom API, I needed to test each endpoint to ensure it behaved as expected, including validating both input and output. During this process, I discovered that several existing stored procedures required modification. Unfortunately, I did not keep track of which procedures were changed. Once the documentation was complete, I had to go back and identify the stored procedures that had been altered. This experience led me to think more seriously about how to track changes to stored procedures; something that would be valuable for auditing, deployment reviews, and debugging. Having visibility into when a stored procedure was created or last modified can help both developers and database administrators identify recent stored procedure changes. To ad…  ( 4 min )

Sometimes, you may need to duplicate a model instance and create a new one with some custom changes. Instead, you can use Laravel's built-in replicate method: use App\Models\Address; $shipping = Address::create([ 'type' => 'shipping', 'line_1' => '123 Example Street', 'city' => 'Victorville', 'state' => 'CA', 'postcode' => '90001', ]); // Create a replicated instance of the address without saving it $replicatedAddresss = $shipping->replicate(); The previous code creates a new address instance but does not save it to the database. Before saving, you can modify any attributes as needed: ... $replicatedAddresss->type = 'billing'; // Save the replicated instance to the database $replicatedAddresss->save(); Alternatively, you can replace the previous line where the property is assigned with the fill method: ... $replicatedAddresss = $shipping->replicate(); $replicatedAddresss->fill(['type' => 'billing'])->save(); On top of that, you can exclude specific attributes from being replicated by passing them as an array to the replicate method: $shipping = Address::create([ 'type' => 'shipping', 'line_1' => '123 Example Street', 'city' => 'Victorville', 'state' => 'CA', 'postcode' => '90001', ]); $shipping->replicate([ 'line_1', 'state' ]);  ( 3 min )

June 18 2025 Today was one of those days that reminded me why I love tech because it is such a beautiful mix of learning, building, and stepping into new beginnings. 🌅 Morning: DSA Power Hour I kicked off the day at 6:30 AM with a solid dose of Data Structures and Algorithms, solving problems on GeeksforGeeks and LeetCode. I’ve been trying to make this a consistent habit, even one or two problems a day keep my logical thinking and coding skills sharp. Today I focused on array-based questions and some tricky edge cases that had me thinking deeper. 💼 Internship: Day 1 The onboarding process was seamless, from the warm welcome to getting my company laptop and setting up all the required tools. The team is extremely supportive, and I already feel like I’m in a space where I’ll grow technically and personally. Can’t wait to dive into the projects we’ll be working on! 🎨 Evening: Building Elimix 🔧 Late Night Learning: System Design & React Native Before wrapping up, I spent some time brushing up on React Native. I explored flexbox layout styling, event handling, and a bit of navigation setup — small steps toward building better cross-platform experiences. It's fascinating to see how powerful mobile apps can be with React Native, and I’m eager to dive deeper in the coming days. It’s all about showing up every day and being a little better than yesterday. QUOTE OF THE DAY Signing Off Anisha 💗  ( 4 min )

When it comes to deploying resilient and highly available applications in Kubernetes, scheduling constraints are key. Two powerful tools for controlling pod placement are podAntiAffinity and topologySpreadConstraints. While both help manage pod distribution, they serve different purposes and offer distinct advantages. Let’s break down what each does, how they differ, and when to use them. Introduction Imagine you’re running a critical application on Kubernetes. You want to ensure that your pods are spread across different nodes or zones to avoid downtime if a single node fails. This is where scheduling constraints come into play. Kubernetes offers several mechanisms for this, but two of the most important are podAntiAffinity and topologySpreadConstraints. What Is podAntiAffinity? podAn…  ( 4 min )

Getting GitHub Copilot to write end-to-end tests usually requires giving it access to your source code. That’s because Copilot on its own can’t open a browser, explore a webpage, or understand how a UI behaves, so it lacks the context needed to generate accurate tests. But that changes with Playwright MCP (Model Context Protocol). An MCP acts as a bridge between Copilot and the real browser, allowing it to open websites, interact with UI elements, and take snapshots of the page. This unlocks a whole new capability: generating Playwright tests from natural language instructions, even when you don’t have access to the application’s codebase. In this post, we’ll show how Copilot, with the help of the Playwright MCP, can generate, run, and validate E2E tests just by telling it what you want in…  ( 5 min )

Welcome to Week 3 of the "Demolish the Giant" series. This week, we dive into Meta — the company that bet big on a future in virtual reality but ended up chasing ghosts in a laggy metaverse. Mark Zuckerberg, a visionary with relentless ambition, plunged Meta into the metaverse era with Oculus and billions in investment. He saw a future where virtual worlds would replace real ones. But dreams don’t always sync with reality — especially when your VR legs feel like spaghetti. His obsession? Creating a new internet where you live inside the screen, not just look at it. Meta poured billions into VR hardware, software, and social platforms. They built Horizon Worlds — a VR social network that promised endless possibilities. But here’s the catch: users stayed skeptical. Technical glitches, lack of content, and a general feeling of awkwardness kept the metaverse niche at best. Meta’s metaverse was more of a phantom limb than a new reality. While the metaverse lagged, Meta doubled down on collecting your data. VR headsets track every glance, every gesture, every moment of attention. Privacy advocates warn that this level of surveillance inside virtual worlds could become the ultimate data trap. Meta’s real metaverse might be the invasion of your personal space and mind. With the metaverse hype deflating, Meta is pivoting quietly back to its core: social media and AI. But the question remains — can a company so invested in a VR dream admit defeat? Or will Meta keep chasing shadows in virtual worlds while reality moves on? Meta’s metaverse is a cautionary tale of ambition without timing. A vision that’s more glitch than game changer. Mark’s dream to live inside the internet faces a harsh reality: the real world still wins — for now. ✨ Coming Next Week: AMAZON — The Invisible Empire Where convenience meets surveillance and the warehouse meets your doorstep. Stay vigilant. Stay critical. Let the demolition continue.  ( 4 min )

CSS container queries are a powerful feature that allows you to style elements based on the size of their parent container, rather than the entire viewport. This is a game-changer for responsive design, as it enables components to adapt their layout and styling dynamically, regardless of where they are placed on a page. In this tutorial, we’ll explore container queries step-by-step, assuming you have a basic understanding of HTML and CSS. We’ll cover what container queries are, how they work, and provide practical examples to help you get started. Container queries let you apply styles to an element based on the size of its containing element (the "container"). Unlike media queries, which rely on the viewport’s dimensions (e.g., the browser window’s width or height), container queries focu…  ( 7 min )

In today’s fast-paced world, having the right knowledge is important but having the right people in your circle can be just as valuable. Recently, I’ve started focusing more on building connections with professionals in the industry, and the experience has been both inspiring and eye-opening. Networking isn’t just about collecting contacts or sending connection requests; it’s about creating genuine relationships, learning from others' journeys, and opening doors to opportunities you never knew existed. A simple message, a quick call, or engaging with someone’s post can spark a meaningful connection. Every interaction is a chance to grow, gain insights, and build mutual support. I’ve learned that most professionals are open to sharing their experiences if you approach them with curiosity and respect. Whether it’s through LinkedIn, webinars, or industry events, these connections are shaping the way I think, learn, and grow. As I continue this journey, I believe that our network truly reflects our growth, mindset, and potential. Let’s keep connecting and learning together!  ( 3 min )

Hey dev community! Building on AWS? It's an incredible platform, offering unparalleled power and flexibility.

Generative AI is a fantastic tool to use to quickly create images based on prompts. One of the issues with some of these platforms is that they don’t actually store the images in a way that makes them easier to retrieve after they’ve been created. Oftentimes you have to make sure to save it immediately after the process is completed, otherwise, it's gone. Luckily, Stability offers an API that can be used to programmatically generate images, and Tigris is the perfect solution to store those images for retrieval. In this article, you’ll learn how to deploy an app to Fly.io that will allow you to generate images using the Stability API and automatically store them in a Tigris bucket. 💡 Before you can follow this guide, make sure you have a Fly.io account and the fly CLI installed on your com…  ( 8 min )

My Journey with the Hyperlane Framework Introduction As a third-year computer science student, I've been searching for a web framework that could both meet my learning needs and prove useful in practical projects. After several months of exploration and hands-on experience, I want to share my deep dive into a Rust web framework that has completely changed my perspective on modern web development. When I first encountered this framework, I was relatively new to Rust and worried that the learning curve would be too steep. However, once I actually started using it, I discovered that the framework's design philosophy was incredibly user-friendly, allowing even students unfamiliar with Rust to get up and running quickly. use hyperlane::*; #[get] async fn hello_world(ctx: Context) …  ( 7 min )

Hi — I’m Timothy. This post is a reflection — not about regret, but about understanding how we end up making the choices we do… and how sometimes, we grow out of them. The First Shift: Into BSE But I never thought of software as a career. At the time, the word “developer” to me meant IT support, someone fixing printers or helping you reset passwords. I couldn’t yet imagine that people like Elon Musk or Bill Gates also started with code — and used it to build entire systems and companies. When it came time to choose a major, I followed the advice around me. People said BSE had good career prospects, it was practical, and in demand. So I transferred universities and committed to the path. I didn’t know much about HVAC systems, fire services, or green buildings — but I was accepted, and I be…  ( 5 min )

This week’s episode: how I accidentally DDoS’d our own backend... from inside the backend. We had a microservice A that relied on service B for fetching customer data. One fine morning, I decided to make our request to service B more “resilient.” Added a retry block using the new HTTP client wrapper. Something like: for _ in range(3): try: response = call_service_b() break except: time.sleep(1) Looks harmless, right? Well… Here’s what I missed: Service B was already failing due to a separate deployment issue. The retry logic was not exponential, and ran for every request. Service A was deployed to all nodes, each now retrying every request 3 times. Multiply that by: 5K requests per second 3 retries 6 instances 🎉 Congratulations! You just self-DDoS’d your own service. Both A and B went down in under 90 seconds. Retries aren’t magic. Add exponential backoff. Add limits. Add circuit breakers. And most importantly add rate limits, yes even for internal requests. Log retries explicitly. So you don’t have to grep through 500MB of logs later. Monitor retry rates—because a spike might be hiding a deeper issue. ✅ The Fix We rolled back, patched in exponential backoff + error rate logging. Trying to make things more reliable can backfire spectacularly if you forget to put guardrails. Don’t just retry. Retry wisely.  ( 3 min )

As a DevSecOps engineer, my daily grind usually involves CI/CD pipelines, security audits, and infrastructure as code. So, when the "Build Games with Amazon Q CLI" campaign popped up, it was a refreshing detour from the usual. The idea of conjuring a game with just conversational prompts, powered by Amazon Q CLI's Claude 4 large language model, was too intriguing to pass up. This isn't the usual realm of an "enthusiast" for me, but more of an exploration into how AI can augment a developer's toolkit, even outside their primary domain.

Let’s be honest, PostgreSQL is great, but documenting its schema isn’t. You open the database, and all you get is a list of tables. If you’re lucky, maybe a few constraints. But if you actually want to understand how the database works, or explain it to someone else... good luck. I’ve seen this problem a lot, especially in teams. Everyone assumes someone else is handling the documentation. Then months later, you’re stuck trying to figure out what client_log_v2 was meant to do. That’s why I started using DbSchema. It gives you diagrams, interactive docs, and actual context, without having to dig through SQL files or guess what each table is doing. Here’s how I document PostgreSQL databases now.

Dynamic Decision Making: Systems that employ AI-driven tool calling to determine execution paths based on real-time context, rather than following predetermined logic flows. The dynamic nature of these systems presents a unique challenge: understanding the flow of logic becomes increasingly complex as the system scales. A single query might trigger no tool calls, while another could initiate a cascade of nested interactions where AI agents themselves trigger additional tool calls. This complexity makes system behavior d…  ( 7 min )

型安全な開発 JavaScript (JS) は非常に柔軟な言語ですが、その柔軟性ゆえに、特に大規模なアプリ開発では予期せぬエラーやバグ発生のリスクが高くなります。そこで登場するのが、TypeScript (TS、タイプスクリプト) です。 TypeScriptは JavaScript に「型」の概念を加えたスーパーセットです。 TypeScript を使うと、記述したコードの型が正しいかどうかを、アプリ実行前にチェックしてくれます。これにより、以下のようなメリットがあります。 メリット 説明 開発効率の向上 型定義により実装者の意図が明確になる。コード補完が強化される。 バグの早期発見 アプリ実行前に、型の不一致としてエラーを検出でき、修正コストを削減できる。 コードの可読性・メンテナンス性 型情報により、コードの意図が明確になり、共同開発や長期運用の助けになる。 開発効率の向上: コードを書いている最中に、変数や関数の型が明確になるため、どのようなデータを受け取るか、何を返すかを迷うことが少なくなります。 エディターの自動補完が強化され、タイプミスや関数名の間違いなどが減ります。 バグの早期発見: コンパイル時に型の不一致などのエラーを検出できます。開発の早い段階でバグを見つけることができ、実行時エラーで検出する場合と比べて、修正コストを削減できます。 コードの可読性とメンテナンス性の向上: コードに型が明記されているため、他の開発者 (または未来の自分) がコードを読む際に、データ構造や関数の意図を理解しやすくなります。 大規模なプロジェクトや複数人でのチーム開発において、コードの品質を保ちやすくなります。 // JavaScript function greet(name) { // name が文字列であることを期待している // しかし **数値やオブジェクトが渡されてもエラーにならない** // その結果、予期せぬ挙動になる可能性がある return 'Hello, ' + name } console.log(greet('Alice')) // "Hello, Alice" console.log(greet(123)) // "Hello, 123" (もっと複雑なコードでは意図しない結果になる可能性) // TypeScript // name は必ず文字列、戻り値も文字列であることを明示 function greet(name: string): string { return 'Hello, ' + name } console.log(greet('Alice')) // "Hello, Alice" // console.log(greet(123)) // エラーまたは警告: Argument of type 'number' is not assignable to parameter of type 'string'. // 意図と異なる型のデータを渡そうとするとエラーや警告が出るため、 // 関数作成者と使用者それぞれで安全なコード記述ができる このように、 TypeScript を導入することで、より安全で堅牢なコードを書くことができるようになります。  ( 3 min )

Hi Devs 👋 Last week, I launched MintYourMood, a React-based PWA that lets users turn their mood into a custom-designed NFT — and mint it on the Polygon blockchain. Built with React + Thirdweb, this project was a mix of frontend fun and Web3 logic. Here’s how (and why) I built it. 🎯 The Idea What if you could turn your mood of the moment into an NFT — a little capsule of emotion minted forever? And that’s how MintYourMood was born. 🧱 The Tech Stack Frontend: React + TailwindCSS PWA: Fully installable (Add to Home Screen) Web3: Thirdweb SDK for wallet connections, NFT minting, storage Storage: IPFS via Thirdweb's upload Design to NFT: html-to-image + IPFS Chain: Polygon (MATIC) ⚙️ How It Works User inputs: emoji, name, quote, selfie Visual generation: The app creates a mood card using html-to-image IPFS upload: Both image + metadata get uploaded Minting: Via mintWithMetadata() on a custom ERC-721 contract All done inside the browser. No backend required. 🧪 Dev Challenges React hydration and conditional Web3 hooks — caused some tricky race conditions. IP geolocation block — added basic client-side check to restrict access in high-risk countries. Cookie storage duration logic and syncing across tabs (localStorage + storage events). 🧠 What I Learned Thirdweb is fantastic for Web3 projects — wallet connect, contract calls, IPFS — all in one. User privacy handling is essential in crypto apps — even for something as light as emoji NFTs. Dev-first NFT tools make launching onchain experiences smoother than ever. 🖼️ Try It Out 🔗 https://mintyourmood.com Give it a spin and mint your current vibe. Got feedback, ideas, or bugs?

For decades, SQL has been the backbone of data querying. But as machine learning and natural language interfaces become more mainstream, a growing number of teams are asking: Can we make our accounting systems smarter than traditional SQL allows? The answer lies in vectorizing structured accounting data. In this article, we’ll explore why product managers and engineering leads should consider vectorization for structured accounting data — especially in the age of AI. You’ll learn how it works, how to implement it, and how it opens doors that SQL simply can’t. Structured accounting data (invoices, journal entries, bills, etc.) maps beautifully to relational databases. But traditional SQL querying has limitations: Exact matching bias: SQL excels at filtering exact matches (e.g., WHERE custom…  ( 6 min )

Stock price data is everywhere online, meaning opening, closing, high, low, volume, and a bunch of indicators based on them. It’s free and easy to get. On the other hand, other types of data that could be useful for forecasting, like financial statements or market sentiment, are often harder to find, and can be really (sometimes really) expensive. Because of that, a lot of people have tried to predict the stock market using just price data, especially the closing price. You can find plenty of articles showing models that seem to do a good job, with predicted prices that look very close to the actual ones. But in many cases, these articles don’t include proper evaluation, even basic metrics like MAE or MSE are often missing. So that got me thinking: Can we actually forecast stock prices usi…  ( 14 min )

1. Introduction to Spring Framework The Spring Framework is a powerful platform for developing Java applications. It started in 2002 and helps developers build secure, efficient, and maintainable software. Think of Spring as a toolkit that organizes and wires up all the parts of a Java application so you don’t have to do it manually. Inversion of Control (IoC) and Dependency Injection (DI)—fancy terms that simply mean Spring creates and manages the objects your app needs and connects them together. Traditional Java EE (Before Spring): Spring’s Solution: Less code: Write only what’s necessary. Better testability: Easily test parts of your app without starting the whole app. Simpler wiring: Let Spring create and connect the objects. Legacy Java EE Architecture: • Tightly coupled component…  ( 5 min )

Let’s start with a question that’s been bugging AI researchers for years. Why do tiny, almost invisible changes in an image completely throw off deep learning models? You show a photo of a panda. The model confidently says “panda.” Then you tweak a few pixels — changes you probably wouldn’t even notice — and suddenly it screams “gibbon.” That’s not just weird. It’s dangerous in real-world systems like self-driving cars or medical diagnostics. This kind of failure is what we call an adversarial attack. And the usual defenses? They mostly involve tweaking the inputs or training models to resist certain attacks. But these fixes are limited. They patch symptoms without solving the root cause. So we asked a deeper question: What if robustness isn’t about fighting off attacks at the input level?…  ( 5 min )

In Java programming, the term "flag" typically refers to a variable used as a signal or indicator within a program's flow. It's a common programming concept, not specific to Java, but widely applied in various contexts within Java development. Boolean Flags: The most common type of flag is a boolean variable. It holds a true or false value, indicating whether a specific condition has been met or a particular state exists. Sample program : boolean foundEven = false; for (int num : numbers) { if (num % 2 == 0) { foundEven = true; // Set the flag break; } } if (foundEven) { System.out.println("An even number was found."); } REFFERED LINKS: https://www.quora.com/How-can-the-flag-be-used-in-a-Java-program https://www.geeksforgeeks.org/use-of-flag-in-programming/  ( 3 min )

TL;DR: AI isn't replacing skilled developers; it's a powerful tool that augments their work, enabling higher-level problem-solving rather than substituting deep understanding.. The "programming bubble" burst: Many developers, especially those from rapid bootcamps, often lack the foundational depth needed for complex problem-solving, making them vulnerable in a maturing market. AI growth faces inherent limits: Current AI, particularly LLMs, operates within computational and data constraints. Its progress follows an "S-curve," not infinite exponential growth, and widespread quantum computing is still far off. True builders will thrive: Developers who possess deep computer science fundamentals, understand how to build robust systems, and can critically assess AI-generated code will find their…  ( 10 min )

Throughout our CMS development series, we've progressively enhanced our application's functionality.

Let's dive into the implementation: We already added a "Preview" button to our "Actions" menu for each post, and now we will simply finish with its functionality. add the "onClick" event to the "Edit" button, inside our "TableComponent", with the "handlePreview" function with two parameters; handleEdit(selectedItem, event)}>Edit</MenuIte…  ( 8 min )

In our last article, we organized our test data into collections with Arrays and structured it with Objects. We built a clean toolbox. Now, it's time to add power tools. This article is about breathing life into your scripts. It's about writing code that can repeat actions, make decisions, and be reused. We'll focus heavily on a core principle of software development: DRY (Don't Repeat Yourself). Writing the same code over and over is slow, error-prone, and a nightmare to maintain. We'll tackle this by mastering TypeScript's fundamental logic: Functions, Loops, and Conditionals. By the end, you'll be able to write automation that isn't just a series of steps, but an intelligent, robust system.

Bridging Design and Code with Image-to-Compose UI The Declarative Advantage of Jetpack Compose Okay, so, Jetpack Compose is kind of a big deal. Instead of messing around with XML, you describe what you want your UI to look like using code. This declarative approach makes things way easier to understand and maintain. Think of it like telling a story instead of drawing a blueprint. You say what should happen, and Compose figures out how to make it happen. It's a different way of thinking, but once you get the hang of it, you'll wonder why you ever did it the old way. Plus, it plays super nice with Kotlin, which is another win.

Originally published by Cyril Scetbon on June 16, 2025 In my previous post, I explored why SurrealDB is unlike any other database: it blends document, graph, relational, and vector models into one engine - and it's written in Rust. That flexibility makes it a perfect match for Rig.rs, a toolkit for building LLM-native agents in Rust. Today, I’m going to show exactly how the two fit together by building a basic knowledge agent - one that embeds word definitions and answers questions using that content without having to manage the lookup yourself. Let me rig this thing. 🔧 I’m building a context-aware support agent that: Ingests internal documents Embeds them into vector space Stores everything in SurrealDB Finds relevant documents using cosine similarity Passes those to an LLM to generate a…  ( 5 min )

Imagine this. You’ve just added your favorite shoes to an online cart. You tap “Buy Now.” The screen flickers. Within two seconds, it confirms: “Payment Successful.” Simple, right? But what if I told you that behind that one tap is a fast-paced digital relay race—one that determines whether you get your shoes, or a payment failed notification? Welcome to the hidden world of payment gateways. At its core, a payment gateway is the tech bridge between your business and the banks. It encrypts data, validates the card, talks to processors, and returns an instant “approved” or “declined” result. It does all this in under 3 seconds. But that’s just the surface. Let’s look deeper. 🔍 The Silent Hero in Business Growth A great payment gateway isn’t just about processing payments—it’s about winning …  ( 4 min )

A Segment Tree is a data structure that stores information about array intervals as a tree. This allows answering range queries over an array efficiently, while still being flexible enough to allow quick modification of the array. This includes finding the sum of consecutive array elements a[l... r], or finding the minimum element in a such a range in O(log n) time. Between answering such queries, the Segment Tree allows modifying the array by replacing one element, or even changing the elements of a whole subsegment (e.g. assigning all elements a[l...r] to any value, or adding a value to all element in the subsegment). You are given an array A[], and you want to perform: Range queries: e.g., find the sum, minimum, or maximum in a subrange A[l...r]. Point updates: change a value at a speci…  ( 5 min )

On June 16, 2025, WhiteBIT Coin (WBT) reached a new all-time high of $52.27, following a series of steady price gains throughout the year. Unlike many digital assets that rely on speculative volatility, WBT’s growth trajectory appears tied to fundamentals: controlled supply, tangible user utility, and a deepening ecosystem. This article examines the underlying mechanics behind WBT’s rise and outlines three plausible development paths for the asset through Q3. WhiteBIT Coin has demonstrated consistent appreciation, with historical breakpoints at: • $28 on January 17 • $30 on March 2 • $32 on May 25 • $35 on June 12 These steady gains point to organic accumulation rather than hype-driven volatility. The most recent jump to $52 indicates growing demand, possibly accelerated by exchange-…  ( 5 min )

Alright, let me be honest right out the gate: I always thought Vim was just some arcane flex tool for terminal nerds. You know — the kind ThePrimeagen uses at lightspeed while yelling "LET'S GO!" on stream. It looked cool. It sounded fast. But it also looked like a keyboard-induced migraine. Still… I was curious. So I decided to see what the hype was all about. Day 1 with Vim felt like: "How do I quit?" "Why can't I type?" "Oh cool, I deleted the entire line again." It was confusing. It was rigid. It felt like Vim was a gatekeeper, not a helper. I legit thought, "This is just a thing YouTubers use to feel cool." And maybe it is — a little. But I kept going. Somewhere around day 3 or 4, I stopped trying to fight Vim. I started noticing that: The modal editing wasn't stupid — it was intentio…  ( 4 min )

The threats to cybersecurity are occurring at an unprecedented rate, and therefore, security testing must ensure organisational protection. External network penetration testing plays a pivotal role in helping you discover the vulnerabilities that can be used by malicious individuals outside your network perimeter. ** ** ** Public-facing web applications and services ** Automated tools do provide broad coverage; however, complex vulnerabilities are likely to be identified using manual techniques. Both methods offer the most comprehensive evaluation possible. ** ** ** Automated domain scanning, subdomain enumeration, and service fingerprinting are all great reconnaissance techniques that will help uncover meaningful information that will assist us in our next steps in the testing process. ** You will need to consider the exploitation frameworks you select for assessment and develop a careful methodology or protocols for testing the possible vulnerabilities that you exploit. Record all your findings, including steps to reproduce those findings, and document the potential impacts on the organisation's business. ** ** Social engineering awareness training complements technical testing by addressing human vulnerabilities that technical tools cannot detect. Combining network testing with social engineering assessments provides a comprehensive security evaluation. ** ** ** ** ** ** ** Want to improve your external security posture?

Hey friends! 👋 It’s a new week and I’m back with another quick, easy tutorial. This time we’re talking about JavaScript objects. Objects used to confuse me a little. Now I just think of them as mini folders storing related info. Let's break it down. Object? An object in JavaScript is like a shopping cart 🛒. const cart = { 'item-name': 'Laptop', price: 2000, quantity: 1 }; Here: 'item-name' is the key and 'Laptop' is its value: this tells us what’s in the cart. price is the key and 2000 is the value: how much the item costs. quantity is the key and 1 is the value: how many you're buying. So instead of remembering each piece of info separately, you group it all inside one neat object: your cart 🛒. It makes data easy to organise, update and use You can use dot notation: console.…  ( 5 min )

For many students, learning algorithms starts in a classroom, surrounded by whiteboards filled with graphs, loops, and pseudocode. It's easy to assume these abstract concepts exist only for exams or coding interviews. But step outside the classroom, and it becomes clear that algorithms shape far more than academic success—they influence our daily routines, business decisions, and digital experiences in ways we rarely notice. Take your morning commute, for instance. When you open a map app to find the fastest route, it doesn’t just show streets. It runs complex algorithms—like Dijkstra’s or A*—to evaluate traffic, road closures, and travel time. The result? A path optimized for speed and efficiency, all computed in the background within seconds. Online shopping is another area where algorit…  ( 4 min )

Disclaimer: I built Myriade (and I love it ^^) Let’s be honest: writing SQL can feel like a chore — tedious and tricky. Myriade is an AI-powered tool designed to make database queries easy and intuitive. — no SQL needed. Start by hooking up your Postgres database to Myriade. Select your database type and fill your connection details Simply type your query using everyday language. For example: “What were the sales figures last quarter?” “Explain the decrease in user sign-ups yesterday.” You don’t even need to worry about field names or tables — Myriade figures that out for you. After you ask, Myriade transforms your plain-English question into SQL, fetches the data, and presents clear results as tables, graphs, or easy-to-understand insights. Using a database about Formula 1 Data security matters, so Myriade comes with built-in privacy: Read-Only Mode: No chance of accidentally editing or losing data. Sample Only: The AI only reads a sample of the results (like a human would) AI — Zero Data Retention: Nothing you query gets stored on the AI providers. Zero Knowledge Protection: Advanced features to hide your sensitive data from AI providers. Myriade isn’t just for basic queries. Here are some practical scenarios you can try: Diagnose a Problem: “Why did sales drop on March 10?” Find What’s Missing: “What key metrics aren’t in our monthly reports?” Shape Your Data: “Make a quick table showing each user’s last purchase.” Check Your Data Quality: “Spot any weird duplicates in billing data.” With Myriade, interacting with your database feels less like coding and more like chatting. myriade.ai.

Hey devs 👨‍💻 I just read a post on CMC that really nailed something I’ve been noticing in my own work: broker models are no longer optional for Web3 infra — they’re the new default. A few years ago, exchanges were just backend pipes for liquidity. Today, they’re go-to-market tools, monetization channels, and sometimes the biggest user acquisition engine you’ll ever plug into. That’s a massive shift for those of us shipping wallets, terminals, or anything API-driven. The WhiteBIT case in the article stood out. Their broker model doesn’t just offer API keys and walk away. It gives: Up to 40% revenue share (that’s real money for bootstrapped teams), Custom terms for different product types (finally, someone who gets that a wallet ≠ a DEX ≠ a terminal), Co-marketing and even user tournaments (which can be more effective than paid ads, tbh), Plus: fast onboarding and solid support — which makes a huge difference when you’re on a tight dev cycle. What hit home most? The article also breaks down the Atani x Kraken use case. Worth reading — it shows how good UX, embedded trading, and real-time commission logic actually improve LTV and retention. Something I’ve seen in my own builds too. Anyway, just thought I’d share. If you're building infra and haven't thought about embedded exchange layers or broker monetization, now’s the time.

Rust is known for its blazing-fast performance without a garbage collector and at the heart of that magic lies ownership. For devs coming from languages like Python, JavaScript, or even C++, Rust’s ownership model might feel a little strict at first. But once you get the hang of it, it becomes your best ally in writing safe, concurrent code without worrying about memory leaks or race conditions. Let’s break it down with real-world analogies and simple concepts. In Rust, every value has a single owner—a variable that holds responsibility for it. When you assign that value to another variable, the ownership moves. The original variable is no longer valid. `let book = String::from("Rust Book"); let borrowed = book; // book is moved here // println!("{}", book); ❌ Error: book no longer owns t…  ( 4 min )

Hey dev.to community! In my very 1st post where, I have decided to learn django by building small projects. Here is an update on my progress: Did the initial project setup and created a Products app. Created a Product model with slug field which is generated automatically. With slugs SEO-friendly URLs can be created(will write more about this in future post). Created RESTful endpoints(GET, POST, PUT and DELETE). Create Product serializer. I am amazed by how using a few lines of code these APIs can be written utilising Django REST framework generic views. These generic views simplifies the creation of API endpoints for performing CRUD operations. For example, in this project I have created just two views which handles CRUD operations in few lines of code. ProductListCreateView: Uses generics.ListCreateAPIView to get list of all the products(via GET request) and create a new product(via POST request). ProductDetailView: Uses generics.RetrieveUpdateDestroyAPIView to get a single product(lookup based on slug field), PUT request to update a product, DELETE request to remove a product. Another good thing is, Browsable API provided in DRF. One can interact with APIs, test and debug it. Next, I will be working on Categories of the product, expand CRUD operation to categories and get into django admin interface. Also attached some screenshots of the APIs and code. Complete code available here.  ( 3 min )

Introduction Yes, GraphQL can call REST APIs. In fact, this is a common way to use GraphQL in real projects. It lets you use your existing REST services while giving frontend apps the flexibility of GraphQL. In this article, you’ll learn how to call REST from GraphQL using a very simple and practical method. Many apps already have REST APIs. Instead of replacing them completely, you can wrap those APIs with GraphQL. This lets frontend developers ask only for the data they need, without changing your backend. You get the best of both worlds: Use existing REST endpoints Expose a cleaner GraphQL API to clients We’ll create a GraphQL server using Node.js, and we’ll call a public REST API: https://jsonplaceholder.typicode.com/users/:id This is a fake REST API that returns fake user data.…  ( 4 min )

In this blog, I’ll walk you through a simple yet effective C++ program that uses classes and objects to manage student scores and determine how many students scored more than the first student. Let’s break it down together! 🧩 We have a group of students. Each student gives five test scores. We want to calculate how many students scored more than the first student. Simple, right? Now let's dive into how this is achieved using classes in C++. class Student { private: int scores[5]; // Each student has 5 scores public: void input(); int calculateTotalScore(); }; We define a class Student to encapsulate the scores and operations. scores[5] is a fixed-size array holding 5 test scores. input() allows entering the scores. calculateTotalScore() adds up the scores. void Student::inpu…  ( 5 min )

Today, I'm going to share about lazy loading in the Cangjie development language. First, let me explain to the beginner friends what lazy loading is. Lazy loading is called LazyForEach in the code. Judging from the name, you can surely guess that its function is similar to that of ForEach. Unlike ForEach's one-time loading of all data, lazy loading loads data on demand based on the available area of the screen. Moreover, when the content slides out of the screen range, lazy loading automatically destroys this content. Therefore, lazy loading significantly optimizes the performance of the program and greatly improves the user experience. This point has already been compared by Youlan Jun in the ArkTs language. When there is a large amount of data, it is strongly recommended that everyone us…  ( 4 min )

Disclaimer: This content is for educational purposes only. I still remember the launch day of our first progressive web app (PWA). We had tested everything — or so we thought. But when users started pouring in, so did the bugs. Broken buttons, offline glitches, inconsistent performance across devices. It was a nightmare. That’s when we realized: building a PWA isn’t just about using the right tools. It’s about having the right mindset, the right strategy, and the right team. Fast forward to 2025, and the landscape has matured. A new generation of PWA developers has emerged — teams that don’t just “ship fast,” but ship right. They’ve solved the bugs. They’ve squashed the delays. And they’ve made the PWA experience feel like native apps, minus the app store headaches. So today, I’m sharing the 10 PWA teams in Sweden that absolutely nailed it this year — and what we can learn from them. 1. Bluell AB (Stockholm) 2. Netlight Consulting 3. Creuna (Now part of Knowit) 4. Tretton37 5. Monterosa 6. B3 Consulting Group 7. Iteam 8. Cybercom (now part of Knowit) 9. Valtech Sweden 10. Qvik So… What Sets These Teams Apart? 1. They Design for Offline First 2. They Test in the Wild 3. They Use the Right Stack 4. They Automate Everything 5. They Talk to Their Users The Real Lesson? It’s Not Just About Tech You can use React and still have janky transitions. You can follow “best practices” and still miss the mark. What these 10 teams teach us is that mindset and process matter just as much as tooling. They listen. They iterate. They care. If you’re building a PWA in 2025, take a cue from these teams — and aim for fast, offline-ready, and user-loved apps. Or even better, find the right team and let them take the lead. 😉  ( 5 min )

Enumerated fields in data tables have a limited number of predefined values. Filtering conditions on the enumerated field f are often expressed as f =v1 or f =v2 or ...; f !=v1 and f !=v2 and ...; in; or not in. The database has to compare f with n values. When the data table is large, the number of comparisons will be very high, leading to poor performance, and the performance worsens as n increases. If comparisons can be avoided during filtering, performance will naturally improve significantly. esProc’s aligned sequence mechanism can achieve this effect. The following example uses the orders table to demonstrate how to use aligned sequences, and also compares the performance of esProc SPL and MySQL database in calculating conditional filtering on enumerated fields.

Hey Devs! 👋 I recently started learning front-end development under devsync.in, and one of the first things that clicked for me was how powerful CSS can be. HTML gives you the structure, but CSS? That’s where the magic happens — colors, spacing, layouts, and even animations. 🚀 What is CSS? CSS stands for Cascading Style Sheets, and its main job is to style HTML elements. Think of HTML as the skeleton of your webpage, and CSS as the clothes it wears. Hello, World! Hello h1 { color: green; } I personally prefer external stylesheets — it's how I was taught at devsync.in, and it really helps in keeping things clean and scalable. 📐 Understanding the CSS Box Model One of the most important concepts I've learned at devsync.in is the box model. Each HTML element is a box made of: Content Padding Border Margin Think of it like layers from the inside out. 💡 Pro tip: Add this to your CSS reset: * { box-sizing: border-box; } This makes layout calculations much easier! 🧠 Final Thoughts Learning CSS with the support of devsync.in has been a game-changer for me. It’s not about memorizing every property — it’s about building a solid foundation and experimenting as you go. Once you understand the basics, it becomes way easier (and more fun!) to create beautiful web pages. If you're also learning or struggling with CSS, I’d love to connect and share tips. Drop your thoughts in the comments — let’s grow together! 🌱  ( 4 min )

If you’ve worked in the Microsoft development ecosystem, you’ve likely encountered both .NET and ASP.NET—but do you really know the difference between the two? Knowing when to use which can save your team time, money, and a lot of technical headaches. Let’s break it down in simple terms. 🔍 What is .NET? You can use .NET to build all kinds of applications: Desktop (with WPF, Windows Forms) Web Mobile (via .NET MAUI or Xamarin) Cloud-native apps Console apps APIs Microservices So in short, .NET is the entire framework (or ecosystem) that powers modern applications. 🌐 What is ASP.NET? ASP.NET provides: Server-side web development tools Razor pages & Blazor for UI MVC architecture RESTful API development support Authentication and identity handling There’s also ASP.NET Core, which is the modern, cross-platform version—lighter, faster, and designed for today’s cloud-based apps. ⚔️ ASP.NET vs .NET: What’s the Real Difference? 💡 When Should You Use Each? If you're building a web application or REST API → Go with ASP.NET (preferably ASP.NET Core). If you’re developing a desktop app, mobile app, or background service → Use .NET (and the right toolkit like WPF, MAUI, etc.). If you want cross-platform support, always choose .NET 5+ and ASP.NET Core over legacy frameworks. 🚀 Final Thoughts At ChampSoft, we help teams harness the full power of .NET technologies to build scalable, secure, and future-ready solutions. 👉 Read ChampSoft All Blogs: ChampSoft Blog  ( 4 min )

We’re talking about a larger systemic problem that could have far-reaching implications. Copilot's Impact on Traffic: Microsoft’s decision to embed Copilot across all of its products—from Windows to Office tools—has caused a massive increase in the backend traffic directed to OpenAI’s servers. The issue isn’t just that Copilot is working; it’s that its presence in nearly every Microsoft product is consuming far more resources than anticipated. When you open Notepad or start a simple task in Excel, Copilot might be quietly running in the background, sending requests and consuming resources without you even realizing it.

Leverage: The Promise of Big Gains with Little Capital Leverage trading sounds like a fast lane to profit. Put in a small amount, borrow the rest, and ride a 10× position to a fat payday. Crypto platforms love to flaunt this feature—just a few clicks and you’re controlling thousands of dollars' worth of Bitcoin or ETH. At its core, leverage trading means borrowing money to increase your position size. You commit a portion of your capital (called “margin”) and borrow the rest from the exchange to make a larger trade than your funds would normally allow. To open a leveraged position, you need to provide an initial margin—your skin in the game. Exchanges also enforce a maintenance margin, the minimum equity you must maintain to keep your trade open. You use $1,000 as margin to open a $10,00…  ( 6 min )

In the early days of computing, non-volatile memory was essential for bootstrapping a system. Among the earliest technologies used for this purpose were EPROMs (Erasable Programmable Read-Only Memory), which allowed firmware like BIOS to be stored in a non-volatile yet modifiable format. As computing evolved, so did memory technologies, leading to the widespread adoption of EEPROMs (Electrically Erasable Programmable Read-Only Memory) and flash memory in modern personal computers and embedded systems. This article explores the critical role EPROMs played in early operating systems and how their legacy has transformed with modern EEPROM technologies.

Ever wonder why some developers ship features while others struggle with endless meetings and Slack pings? The secret isn't working longer—it's working deeper. Last month, I show interview of 15 senior engineers from companies like Netflix, Stripe, and Shopify. One pattern emerged across every conversation: they all protect sacred blocks of uninterrupted time. Not 25-minute Pomodoros. Not "quick focus sessions." Two full hours of pure, distraction-free development. The results? One Staff Engineer told me he ships more code in his 2-hour block than most devs do in an entire day.

LeetCode 2966 | Medium | Greedy + Sorting You are given: An integer array nums of size n (where n is a multiple of 3) A positive integer k Your task is to divide nums into n / 3 arrays of size 3, such that in each group, the difference between the maximum and minimum elements is at most k. Return: A valid 2D array of groups if possible. Otherwise, return an empty array []. Multiple valid answers are allowed. We need to split the array into triplets where max difference ≤ k. The optimal approach is: Sort the array: close values come together. Greedily pick every 3 consecutive elements. If the difference between the 1st and 3rd in any triplet exceeds k, it's invalid. This ensures we get the smallest difference across every triplet and maximizes the chance of valid grouping. class Solution…  ( 5 min )

Falling Into the CSS Rabbit Hole (Yes Again), Cleaning Up EC Links, and Planning Visual Improvements Today didn’t go quite as planned, but I still managed to check off a few important tasks. Yet Again, Stuck in CSS Tweaks Most of my time was unsurprisingly eaten up by CSS. I got caught up in adjusting the finer details of the design and before I knew it, hours had passed. It’s easy to fall into that CSS rabbit hole, but there’s something satisfying about refining the look and feel. Even small improvements can make the whole site feel more polished. Cleaning Up EC Links I took some time to clean up and reorganize the multiple EC links I had scattered across the site. It’s still a work in progress, but I’ve started creating a more consistent and intuitive user flow. Better structure means less confusion for the user, and that’s a win. Added New Pages from the Footer I created placeholder pages linked from the footer. There's no real content yet, but having the basic structure in place is a helpful step toward shaping the full site architecture. Sometimes, just laying the foundation helps bring clarity to what comes next. Next Up: Visual Improvements Right now, aside from the hero section, the site is pretty bare when it comes to images. To boost visual appeal, I’m planning to add more photographs and graphics. I’ll be experimenting with placement using the Z-pattern layout, which helps guide the viewer’s attention more naturally across the page. In Summary It wasn’t the most productive day in terms of raw output, but I did a lot of thinking and groundwork. Progress is progress—even when it feels slow. If you’re in the middle of building something too, hang in there. It’s all part of the process. Date: June 17, 2025 tags: portfolio, webdev, copywriting, ux, learning  ( 3 min )

After weeks of planning and designing, we finally made the big move — we started building ITConnect, our platform aiming to connect job seekers with companies in the tech world. We began by translating our interface from Figma into real, working code. But as anyone who has gone through this process knows, the transition from design to development comes with a whole new set of decisions and challenges. Week 1: Setting the Technical Foundation Creating the initial project layout Designing the navigation, footer, and main page sections Building a login system that supports two user types: companies and job seekers Setting up a database with key tables (users, companies, jobs, projects...) Implementing a file upload system for CVs and profile images Our Team & Workflow Erzana – backend logic and database structure Sumea – frontend development, bringing the Figma design to life Isme – authentication and platform security We collaborate daily using: GitHub for version control Discord for communication phpMyAdmin for managing the database Early Challenges & Lessons Learned Handling multiple user roles in a shared login system Securing access to pages based on user type Validating user input and profile data Safely storing uploaded files These problems helped us grow technically and work better as a team. What’s Coming Next? Building a company dashboard to manage job listings and applications Creating a worker dashboard for profiles and CV management Adding a section for freelance project applications Integrating a calendar feature for interviews and meetings We’re excited to keep sharing our progress and the lessons we’re learning along the way!  ( 3 min )

After carefully completing our project design in Figma, we thought the hardest part was behind us. But as soon as it was time to turn the design into a working product, we faced an unexpected challenge: We weren’t sure which technical direction to take. Each of us had different ideas. Some preferred a simpler and more straightforward approach, while others suggested a more modern and flexible solution. We spent time discussing, weighing the pros and cons of each option. What we learned is that this phase of the project requires not just technical knowledge, but also teamwork, compromise, and a shared vision of what we’re trying to build. In the end, we made a decision that felt right for us—as a team and for the goals of the project. In the next post, we’ll share more about the implementation process and the lessons we learned along the way.  ( 3 min )

At 8 PM, I was plating the second-to-last course of a wine dinner for 70 guests. At 3 AM, I was spinning up virtual machines and tearing apart old laptops. I’ve been cooking for as long as I can remember. When real life hit, I jumped straight into the kitchen — and almost never looked back. I tried a few other jobs here and there, but nothing ever really stuck. They paid the bills, sure, but they didn’t interest me. Cooking, though? I had the skills. I could make decent money doing it, and I loved it — so dealing with the chaos and the long hours felt worth it. But somewhere in the middle of all that, something shifted. I’d had a few conversations about IT over the years. My father-in-law teaches it and manages one of the server rooms at Promedica Hospital. Naturally, he likes to talk shop…  ( 7 min )

A student-driven project aiming to bridge the gap between young IT professionals and the companies that need them. Technology is not just code and algorithms. It’s opportunity. It’s connection. This is our idea. And this is our story. Why did we decide to create this platform? At the same time, companies are looking for talent — developers, designers, network engineers — but often don’t know where to find them easily. So, we asked ourselves: What if there was a simple, smart platform that connects both sides efficiently? What is ITConnect? IT talents (students, junior devs, freelancers) can build profiles, apply for jobs or projects, and grow their careers And we’re proud to say: this is being built by three Albanian students, from the ground up.  ( 3 min )

在发布我们的 SDK 时，一个时常需要考虑的问题：我们的新版本 SDK 应该支持哪些“版本”？ 这里的“版本”指代很多的东西，比如： 哪些型号的硬件，如 Intel vs Apple M 或者有没有 LiDAR 和 GPS 的设备 最低的可以用于开发的 macOS 版本 最低的可部署的 iOS 版本 最低可用于开发的 Swift 编译器以及 Swift API 对应的版本，如 4.3，5.0，6.0 等等 …… 作为苹果开发者很幸运：苹果公司和 macOS 已经尽量流线化整条产品线，作为苹果开发者毋需过多关注产品的兼容性——想想过去的 Windows 开发者要一直后向兼容到 Windows95，或者 Android 开发者不仅要兼容到 Android 4.0 还要在各种奇形怪状、性能高低的设备上测试，就庆幸自己手上的活儿已经足够简单；但发布时需要考虑的版本矩阵、排列组合，倒也并非一目了然。 苹果官方文档在这个页面上列出了对应的版本匹配，以方便专业开发者更好地厘清版本号的关联：https://developer.apple.com/support/xcode/ 对于我们 SDK 而言，大体上的策略是每年 iOS 升级为版本 n，则兼容 n, n - 1, n - 2 三个版本。而 Xcode 基本目前也是一年一个大版本号，我们也就秉承着“新的 major 版本 Xcode n.0 发布后的我们 SDK 的第一次更新，升级至要求当前 Xcode n.0 大版本”这样的策略。 这几乎已经足够简单明了，但还是有个小的不足—— 由于 Xcode 每年发布一个 major 大版本后 (Xcode 16.0)，通常有四到五次 minor 小版本的更新 (Xcode 16.1 - Xcode 16.4)，这就要求我们随时跟进 Xcode 更新，确保新的工具链依旧能开发、编译 SDK。同时，还要确保支持的最低版本 Xcode，不会因为 SDK 误用新引入的功能，而无法依赖引用它。因此，团队里几乎每一个开发者，都要安装至少三个版本的 Xcode： Minimum requirement version, e.g., Xcode 16.0 (16A242d) Current released version, e.g. Xcode 16.3 (16E140) Next beta version, e.g., Xcode 16.4 Beta (16F1t) (Before WWDC) or Xcode 26.0 Beta (17A5241e) (after WWDC) 有时，因为切换 Xcode 版本失误，会有不兼容的 API 符号溜进代码里面。好在有重重把关，总有人能在发布前测试发现这样的问题，确保发布的 SDK 不会在某些我们号称支持的版本上不能用。 然而，还是有点儿后怕——如果版本号的问题从 SDE 和 DevOps 眼皮底下都溜过去，最终被用户碰到，也算事故了。除了给每一台部署和测试的机器都装上三个版本的 Xcode，留一堆各种版本 iOS 的测试机以外，还能有什么更好更灵活的办法，来质检版本号呢？🤔  ( 3 min )

The landscape of mobile application development has fundamentally shifted. We're no longer creating apps for a single market or language—we're building experiences that must seamlessly adapt to the diverse linguistic tapestry of our global user base. iOS 26 introduces groundbreaking features that transform how developers approach multilingual app development, moving beyond simple text translation to create genuinely inclusive user experiences. In today's interconnected world, the majority of users are multilingual. A developer in Singapore might code primarily in English but consume content in Mandarin and Malay. A business professional in Beirut might use English for work applications while preferring Arabic for news and entertainment. This linguistic complexity presents both challenges a…  ( 6 min )

By Todd Bernson, CTO of BSC Analytics, USMC Veteran, and Guy Who Treats IAM Policies Like They're Handling Live Ammo Voice AI is cool — until it leaks a customer’s audio file to the internet, ends up on a subreddit, and your CISO faints into a pile of SOC 2 binders. If you’re going to work with AI-generated voices, especially self-hosted ones, you better know how to lock it down. This article breaks down how to secure your voice cloning infrastructure on AWS the way a Marine would: with discipline, precision, and zero tolerance for sloppy access control. Whether you're in finance, healthcare, insurance, or just paranoid (which in cloud security is a virtue), here’s how to bulletproof your deployment. First rule: no service should have more access than it needs. IAM is your gatekeeper. Ever…  ( 6 min )

Cloudflare has announced an update to the enforcement order of its Gateway policies, rolling out progressively between July 14th and July 18th, 2025. The email from the Cloudflare Gateway Product Team explains that while this update will not weaken your security posture or change the traffic filtered by your policies, it does require a review of your configuration—particularly if you have HTTP policies in place. In the current model, Cloudflare Gateway evaluates DNS, then HTTP, and finally Network (Layer 4 Firewall) policies. After the update, the order will change to evaluate DNS first, followed by Network policies, and then HTTP policies. For example, if you have an HTTP policy that shows a block page for a “SaaS application” and a corresponding Network policy that silently blocks traffi…  ( 5 min )

We set out to build a system that could generate and run end-to-end tests automatically with predictable results and minimal input from the user. No recorded flows, no screenshots, no manual setup, just a URL. The system scans the page, builds a structured view using a serialized DOM, and generates test cases based on what it finds. We initially approached UI testing as a reinforcement learning (RL) problem. The idea was to train an agent to “see” a rendered web page: locate input fields and buttons based on screenshots, and act as a human user would. We fed screenshots into an RL model so it could learn where fields and click targets were. After a few iterations into the RL research, we began building a visual dataset and training a multimodal model that combined raw HTML (as text) with c…  ( 7 min )

When building backend APIs with Node.js—especially with frameworks like Express or NestJS—you’ll often find yourself handling user input via req.body, req.query, or req.params. But here’s a subtle trap many developers fall into: Mutating the request payload directly can cause hidden side effects. In this post, we’ll explore: What those side effects are, How Express and NestJS treat the request payload, When you should deep copy the payload, And best practices for safe and predictable request handling. When you mutate req.body, you're changing the original object passed through the entire request pipeline. This introduces side effects—unintended consequences in other parts of your app. // Middleware A req.body.username = req.body.username.trim().toLowerCase(); // Middleware B if (req.body.…  ( 4 min )

🚀 Automate EC2 Web Server Deployment on AWS with Terraform and Remote S3 State Managing infrastructure manually is error-prone and inefficient.

While Vercel only provides packages with the component for Next.js, Nuxt, and Astro, you can enable Image Optimization in any framework with the Vercel Build Output API. The first thing we need to do is tell Vercel that we want to use the Image Optimization API. To do that, we need to modify the bundler to add additional parameters to the .vercel/output/config.json file after the build. TanStack Start uses Nitro under the hood, and it provides an easy way to do this. All you need to do is create the nitro.config.ts file with the following content: export default defineNitroConfig({ vercel: { config: { images: { domains: ["yourdomain.example.com"], // Change to your domain sizes: [ 16, 32, 48, 64, 96, 128, 256, 384, 640, 750, 828, 1080, 1200, …  ( 4 min )

A psychologically-aware Claude is a safer, clearer Claude. I injected a 7-number psychology vector (≈ 50 bytes) into Claude Sonnet’s system prompt. It boosted empathy, risk calibration, and action clarity. In a blind A-B, Claude preferred the vector reply 12-1 (plus one tie). See screenshot for before-after responses and σ-scores. Receptiviti’s API returns 200 quantitative signals for any chunk of text. For this demo I used just seven: emotional awareness risk tolerance conscientiousness analytical thinking affiliation drive openness authenticity Those numbers are normalised (−1 σ to +1 σ) and squeezed into one comma-separated line: [psyvec: -0.2,+0.8,+0.4,-0.5,+0.6,-0.1,+0.3] Place that directly after your system role. It costs virtually zero extra tokens at inference time. • Gemini-style went from generic to empathy-tuned reply Plug-and-play: no model fine-tune, no extra GPUs, works in any prompt flow, vector replies felt more personal Capture ~350 words of user text. Send it to /analyze on the Receptiviti API. Select a subset of salient measures (start with the seven above). Build a psyche vector string and prepend it to your next Claude call.  ( 3 min )

What is git? Git is a distributed version control system, which means that a local clone of the project is a complete version control repository. These fully functional local repositories make it easy to work offline or remotely. Developers commit their work locally, and then sync their copy of the repository with the copy on the server. This paradigm differs from centralized version control where clients must synchronize code with a server before creating new versions of code. Version control, also known as source control, is the practice of tracking and managing changes to software code. Version control systems are software tools that help software teams manage changes to source code over time. As development environments have accelerated, version control systems help software teams wo…  ( 4 min )

Developers deserve to have fun. There was a time when the internet felt magical. I remember going to the library just to create a character on The Doll Palace. At home, I'd spend hours changing fonts with WordArt. But as I grew up, the industry did too. We've shifted away from marquees and glittery cursors. Grown-up me started using ones and zeros to build reliable systems for insurance, banking, and healthcare companies. There's pride in that, but it's harder to justify doing something just because it's fun. That's why I tapped into my inner child and used Goose to build a UI that reacts to users' emotions. Sometimes I want to write every line of code. Other times, I just want a quick dopamine hit from seeing my idea go from vision to execution in minutes. Other developers may relate to t…  ( 6 min )

Working on a client project in a distant country recently presented an interesting challenge. They had a strict requirement, I needed to upload my progress every week so they could monitor the project in real-time. I agreed, though with some initial reluctance. This setup quickly revealed unexpected bugs whenever I moved my code from my local development environment to the live server. One particular issue left me truly dumbfounded: the PHPMailer-powered "send mail" feature worked flawlessly on my local machine, but consistently threw errors on the live server. The solution was simple once identified: I had to rename the PHPMailer folder on the live server to match the exact capitalization used in my require statements. Once I changed it to PHPMailer, everything worked perfectly. If you ever encounter similar "file not found" errors when deploying from a Windows to a Linux environment, always ensure your file and folder naming conventions are precise and consistent down to the capitalization. Adhering to conventional naming standards across both servers will save you countless hours of debugging and a lot of stress.  ( 3 min )

"Your database is a ledger, not a scrapbook." Most apps treat data like a blackboard—constantly erasing and rewriting. CRUD (Create, Read, Update, Delete) is simple… until: You need to audit changes ("Who set this price to $0?") You want to replay history ("How did the system behave last Tuesday?") You accidentally overwrite data with no recovery path. Event Sourcing flips the script: Instead of storing state, you store events that led to that state. But when does it actually matter?

Ok so I've now been using Claude Code for a little over a week. It has supplanted Cursor as my primary tool for AI assisted coding tasks, and the transition was very rapid. In fact, I'm not sure I'm going to continue to pay for Cursor. One of the things that I discovered early on with Cursor was that it would frequently get "lost" in my monorepo. If it ever wanted to run an external command, such as installing another npm dependency, it would do it in the wrong directory (usually the repository root). The same thing would happen when trying to run the linter, or unit tests, etc. Almost every single time, I had to explicitly tell it to run a command in a given subdirectory, or just reject the command altogether and run it myself. To address this problem, I began running searpate Cursor in…  ( 7 min )

Introduction This is the second part of our Nx monorepo series. If you haven't yet, you might want to check out the first article, Nx Monorepo Guide: React & Node Fullstack App, where I talked about setting up an Nx workspace. Now, we'll dive into something more specific, yet very important: how TypeScript works inside Nx. Many developers, myself included, often get lost in all the tsconfig files. Do you find yourself wondering what each one does? I know it can be too much to handle at first. The complexity comes from Nx managing TypeScript across dozens of apps and libraries. Unlike traditional single-project setups with one tsconfig.json, Nx monorepos can have 50+ configuration files scattered throughout your workspace. The challenge is that each project needs its own settings while sh…  ( 12 min )

Backend Developer, you've probably had this situation happen: You finish building your API. Everything works perfectly. You test it ten times on Postman. Then your Frontend Developer shows up frustrated: “Something’s not working... the app is freezing!” You check the code and see that your API always returns 200 OK, even when there's an error — with a JSON message saying "Something went wrong." Meanwhile, the frontend is expecting something like 400 Bad Request to show an error message properly. You're both speaking JSON… but you're not speaking the same language. HTTP Status Codes come in. HTTP status codes are standardized codes sent by the server to indicate the result of a client's request. They aren't just random numbers. They're the core communication language between frontend and ba…  ( 5 min )

You're building with AI — maybe a chatbot, an agent, a writing assistant, or something more experimental. The code is coming together, the idea is taking shape… and then the real question hits: “Which model should I actually use?” Suddenly, you’re lost in a jungle of names: GPT-4, GROK, Mistral, Claude, LLaMA, Gemma... Some are open source. Some are locked behind APIs. Some are fast, others smart, all of them marketed like they’re magic. And every source seems to offer conflicting advice. The truth is: It’s not about picking the best model in the world — it’s about picking the best model for your job. This post is a practical, developer-focused approach to making smart model choices — without the confusion, wasted resources, or marketing noise.

From clean code to clean systems — my journey into system design and the architectural insights that changed the way I build. At the end of May, I made a conscious shift in my learning journey — I dove deep into System Design. It became clear that writing clean, scalable, and maintainable code goes far beyond just knowing a language or framework — it starts with how your entire system is designed. I’ve always believed in the cycle of learn–unlearn–relearn. So I paused, re-evaluated, and redirected my focus toward understanding: What is system design? Why does it matter? When do we need it? This shift opened my eyes to the architectural thinking behind every successful product. I started with: Architecture patterns PRD (Product Requirements Document) — understanding how clear documentation shapes the development lifecycle. Next came Microservices Architecture — and that’s when things got exciting. I explored: Architectural styles and service boundaries API Gateway and NGINX for routing, load balancing, and security The role of asynchronous communication in system performance Version control and project organization also matter. I studied: Monorepo: Single repository for all services/projects Polyrepo: Independent repositories for each service/module Both have their strengths. Knowing when to use one can streamline collaboration and CI/CD processes. I wrapped up with: RBAC (Role-Based Access Control) to structure user permissions ERD (Entity Relationship Diagrams) to visualize data models and relationships across the system To build systems that are clean, efficient, and easy to evolve. System design is helping me see how everything connects — from requirements to deployment. And I’m just getting started. 💬 Are you also diving into system design? Share your experience or favorite resources in the comments! 📌 Connect with me on DEV — that’s where I’ll be documenting the journey further.  ( 4 min )

Introduction In JavaScript, it's common to interrupt processing using throw for error handling. While this enables a form of non-local exit, TypeScript lacks the ability to statically type these thrown errors, compromising type safety. To address this, the Result type offers a way to explicitly model success and failure in a function's return value. Libraries such as neverthrow, effect-ts, and fp-ts are commonly used to introduce this pattern into TypeScript. However, each of these libraries has trade-offs. While neverthrow is relatively simple and user-friendly, it is no longer actively maintained—many pull requests have been left unreviewed for months. On the other hand, effect-ts and fp-ts offer powerful features but come with high complexity and large bundle sizes, which can be overk…  ( 4 min )

Anchoring is one of the most critical aspects of boating, especially for adventurers who explore diverse waters. But what makes the process smoother and more efficient? One key component: the bow roller. 🛥 What Is a Bow Roller? A bow roller is a metal or polymer fitting mounted on the bow of a boat, designed to guide the anchor rode and anchor chain during deployment and retrieval. It allows your anchor to move freely without damaging the boat or creating friction on the hull. 🔧 Types of Bow Rollers Single Bow Roller – Ideal for smaller boats or occasional anchoring. Double Bow Roller – Allows dual-anchor setups. Self-Launching Bow Roller – Uses gravity and angles to deploy the anchor with minimal effort. Adjustable Bow Roller – For larger vessels needing multi-position adjustment. 🔍 Pro Tip: Always choose a roller that suits your anchor type (Danforth, Bruce, Plow, etc.) 🌊 Why Bow Rollers Matter Prevents anchor chain damage to the hull Eases anchor retrieval with windlasses Enhances anchoring safety during rough waters Keeps the anchor secure and stable when underway 🛠 How to Install a Bow Roller Choose a marine-grade stainless steel or aluminum roller. Align the roller with your anchor locker and chain path. Secure it using corrosion-resistant bolts and marine adhesive. Test it with your anchor before hitting the waters. ** Best Bow Rollers for 2025** Lewmar Bow Rollers Mantus Marine Anchor Rollers Sea-Dog Line Bow Rollers These brands offer durability, design flexibility, and compatibility with different anchor types.  ( 3 min )

Handling many-to-many relationships in PostgreSQL using Prisma is straightforward and efficient. Prisma can manage both implicit and explicit many-to-many relations. model User { id Int @id @default(autoincrement()) name String projects Project[] // Many-to-many relation } model Project { id Int @id @default(autoincrement()) title String users User[] // Many-to-many relation } By declaring each side as a list of the other, Prisma knows to spin up a hidden join table for you. Generated SQL Migration When you run prisma migrate dev, Prisma will produce SQL akin to: -- 1.

BioChatter is a new open source Python package (v0.11.1 released June 6 2025) designed to bring conversational AI into biomedical research workflows. This library provides a clean backend interface for integrating large language models with biological knowledge graphs via BioCypher and common biomedical tasks. It abstracts away provider specific details with a unified API for sending prompts, retrieving structured outputs, and handling model completion logic over multiple LLMs. Install the package via pip: pip install biochatter Then initialize and call a model: from biochatter import BioChatter bc = BioChatter(provider="openai", api_key="YOUR_KEY") response = bc.ask("List key genes involved in oxidative stress response") print(response) BioChatter converts your question into a structured query, invokes an LLM, and formats the response as JSON or a DataFrame. It also supports: integration with BioCypher for knowledge graph grounding evaluation metrics such as accuracy and F1 for test sets model agnostic chaining to compare GPT 4, LLaMA, and others BioChatter streamlines building apps like gene disease extractors, literature summarizers, or dialog agents for molecular data without scaffolding each component manually. The built in evaluation framework lowers the barrier for reproducible benchmarks in biomedical NLP. Researchers working on hypothesis generation, clinical extractive tasks, or biomedical QA now have an easy way to prototype and compare conversational AI pipelines. Explore documentation and examples at the GitHub repo. Start experimenting by connecting to your lab’s knowledge graph or loading custom biomedical prompts. Share your use cases and help grow the community. BioChatter lays the foundation for more conversational and data driven tools in biology, offering a versatile core for integrating LLMs thoughtfully into scientific workflows.

For years, Cloudflare’s WAF has been my go-to solution for protecting web applications. It’s easy to use, has strong threat intelligence, and offers features like rate limiting, bot mitigation, and challenge pages. However, it’s not without downsides—especially for those of us who prefer control, transparency, or simply want to avoid recurring costs. Recently, I set out to find a self-hosted alternative that could meet my needs without compromising on protection. After testing several options, I discovered SafeLine, a powerful, open-source Web Application Firewall that has now fully replaced Cloudflare WAF in my stack. Here’s how and why. Cloudflare is great, but: Advanced WAF features are locked behind paywalls, for example, number of rules. It depends on third-party infrastructure, whic…  ( 4 min )

Meteor 3.3 slashes build times by around 60% on average, with some projects building over 3× faster builds. This is the first major update to the Meteor bundler in years, introducing several optimizations. The main change is switching from Babel to SWC for transpiling and minifying to speed up builds. We reviewed and optimized the bundler’s components to improve the development experience.

The Map state of AWS Step Functions returns an array of arrays as a result. For further processing, we often need to flatten this result into a simple one-dimensional flat array. With JSONPath, this can be accomplished using the [*] expression as described in the AWS docs: "ResultSelector": { "flattenArray.$": "$[*][*]" } AWS docs for JSONPath Recently, AWS Step Functions introduced JSONata as an alternative query language to JSONPath. However, since this feature is quite new, you won't find much information on how to accomplish the same with JSONata. At least, this section didn't make it into the AWS docs for JSONata yet. In JSONata you can use the .* expression to flatten an array of arrays: JSONata Exerciser However, you must be aware that this expression returns nothing if the result array is empty: JSONata Exerciser In JSONata, you can usually append [] to an expression to cast the result to an array, even if it has only one value: JSONata Exerciser However, this trick doesn't work in this case as both [].* and .*[] will return nothing: JSONata Exerciser The correct way to handle it is a simple ternary condition using the $exists() function: JSONata Exerciser If the expression $exists(states.result.*) evaluates to nothing (falsy value), it will return an empty array as a fallback. You may ask yourself if there is a shorter version using a short circuit || or null coalescing ?? operator like in JavaScript: states.result.* ?? []. Unfortunately, this remains an open issue.  ( 3 min )

Next day's focus was all about TypeScript, and it opened up a new way of thinking about code for me. I’ve always been comfortable with JavaScript, but this statically typed superset challenged me in a good way. We started by covering the basics — type annotations for variables, function parameters, and return values. Then we moved into more advanced concepts like interfaces, type aliases, and optional vs required properties. It felt a little rigid at first, especially coming from JavaScript's flexibility, but the benefits quickly became clear. I built a simple to-do app and used TypeScript to define the shape of each task, enforce valid input, and handle errors gracefully. By the end, my IDE was catching mistakes before I even ran the code — something JS never gave me. That sense of confidence and clarity was super motivating. One thing that stuck with me: “TypeScript makes you design your data before writing the code.” That discipline made my logic cleaner and more reusable. It also made debugging easier because everything was more predictable. I can already tell that TypeScript will be central to how I build both backend and frontend features going forward — and I’m actually excited about that. 💬 Question for Readers: How has using TypeScript changed the way you think about writing JavaScript? Did it help you avoid bugs, or did the strict typing feel like a barrier at first?  ( 3 min )

Leaderboards are everywhere in AI these days. They help us compare models, track progress, and decide which ones are worth our time and resources. But sometimes, a model's top score might raise an eyebrow—almost like it knew the answers ahead of time. It’s easy to assume the highest-ranked models are the smartest or most capable. But in reality, there’s a subtle issue that can throw these rankings off. And while it might sound like cutting corners, it’s not always that simple—or even wrong. In this article, we’ll take a closer look at how this issue impacts model evaluations, why it’s more common than you might think, and how, when handled carefully, it can actually make models more useful in practice. Think of training an AI model like preparing a student for an exam. Now imagine if that …  ( 5 min )

Passing argument by object reference, you will not understand in coding level it more of memory thing how memory work for passing an argument I will give you two example from python and C. Creating my_box: Python creates a dictionary {"item": "old toy"} at some memory address, say 0x1234. my_box is a variable that holds the reference 0x1234 (the address of the dictionary). Calling change_box(my_box): The function change_box gets a copy of the reference 0x1234, stored in its parameter box. Now, both my_box (outside) and box (inside the function) point to the same dictionary at 0x1234. 3.Modifying the Object: When box["item"] = "new toy" runs, it modifies the dictionary at 0x1234. Since my_box still points to 0x1234, it sees the change ({"item": "new toy"}). What If We Reassign? (Uncomment the line): If you uncomment box = {"item": "another box"}, Python creates a new dictionary at a different address, say 0x5678. Now, box points to 0x5678, but my_box still points to 0x1234. The original dictionary (my_box) remains unchanged. num is stored at some memory address, say 0x1000, with value 10. The function try_to_change gets a copy of num’s value (x = 10) stored at a different address, say 0x2000. Changing x only affects 0x2000, not 0x1000. Passing by Reference Using Pointers I know this topic is complicated, not easy to understand. But please do let me know which part you don't understand. This is easiest way to understand.  ( 4 min )

A website can load its content in a flash, but if users can't click, scroll, or interact with it, the experience feels broken. This delay, known as Time to Interactive (TTI), is often caused by third-party scripts (for analytics, chat widgets, etc.) blocking the main thread. At NextBlock CMS, we're engineering a solution to this problem from the core. We are meticulously auditing every script and using the Next.js component to load them intelligently, ensuring your site becomes interactive as quickly as possible. Our approach uses two key strategies: strategy="afterInteractive" for Essential Scripts: For scripts that are important but not critical for the initial render (like analytics), we use this strategy.

Git Hooks are awesome - in theory.

🎯 Objective Demonstrate how to exploit a blind SQL injection vulnerability when: The application does not return any visible output. Error messages are suppressed or handled gracefully. No conditional response difference is observed. In such cases, we can use time-based blind SQL injection — where the attacker forces the database to wait (delay) for a certain amount of time depending on whether an injected condition is TRUE or FALSE. This delay allows us to infer sensitive data one character at a time based on how long it takes for the HTTP response to arrive. Key Concepts 1️⃣ Blind SQL Injection A type of SQL injection where the attacker cannot see the results of their query. There's no direct output or error message returned from the application.

Because sometimes, the best way to understand a framework... is to try rebuilding it from scratch. Frameworks are like magic tricks — they look simple on the outside, but try to reproduce one, and you’ll realize just how many hidden mechanisms are involved. Cloning a web framework forces you to confront questions like: How is routing resolved? Where does state live? How is middleware applied? What happens when an error is thrown? Can you express a feature without undocumented coupling? In short: cloning exposes architecture. And architecture, not syntax, is where complexity hides.

Scenario In my project, we have over 10+ users with access keys. Most of the access keys were 300–400 days old. Having access keys lying around for a long period poses a security risk, which is unacceptable. They’re not just a minor security issue — they’re multimillion-dollar liabilities. The issue I can see is that no one remembers to rotate the access keys, so I thought of building a Lambda function that could remind the team to rotate the keys after a certain number of days. Different organizations enforce varying rotation policies — some require rotation every 30 days, others allow 60 or 90 days before access keys must be refreshed. My solution needed to accommodate these different requirements while being easy to deploy and maintain. In this blog post, I’ll walk you through the com…  ( 9 min )

Caching is difficult to get right and often means you need to pull in additional frameworks into your code. Fine tuning the balance between performance and data freshness takes time and experience. In case of User-Agent integrations (for example, an application UI running in your user’s browser), it is even more crucial, as the User-Agent is rarely under your control and yet demands fast response times. This is why often I opt to provide cache recommendations for the service side in many cases. One such example of this in the product I work heavily with Authress. That doesn’t mean you can’t cache returned values for longer. I'm going to use Authress as example for caching, so a quick summary might make sense.

In the mobile-first world, users expect seamless navigation between apps and websites. Deep linking bridges that gap by allowing you to link directly to specific content within a mobile app, and in Flutter, it's easier than ever to implement. In this blog, we’ll dive into what deep linking is, why it matters, and how to implement it in your Flutter application. Deep Linking refers to the practice of launching an app and opening a specific page (or route) within it using a URL. For example, clicking a link like myapp://product/123 opens the product detail page for item ID 123 in your app. There are three main types of deep links: 1. Traditional Deep Links: Work if the app is already installed. 2. Deferred Deep Links: Work even if the app isn’t installed; the user is taken to the app store f…  ( 7 min )

Streamlining Design to Code with AI AI is changing how we build Android apps, especially when it comes to turning designs into actual code. It's not about replacing developers, but more about giving us tools to work faster and smarter. I've been playing around with some AI-powered solutions, and it's pretty wild how much time they can save. Automating UI Generation for Kotlin One of the coolest things is how AI can now generate UI code directly from design mockups. Forget manually coding every button and layout – AI can analyze a design and spit out the Kotlin code for it. It's not always perfect, of course. You still need to tweak things and make sure everything is pixel-perfect, but it gets you a huge head start. I remember spending hours just setting up basic layouts, and now AI can do…  ( 5 min )

The Interview That Changed Everything Let me take you back to an interview we had—not long ago—with a candidate whose résumé was an actual masterpiece. MIT grad, five languages, built half the tools your team probably uses. But somewhere between, “Tell us about your last team project,” and “How do you handle feedback?” we realized… something was off. No eye contact. No energy. The moment we brought up clients or communication, the vibe dipped like a bad internet connection. We didn't hire him. It wasn’t about skills. It was about fit. And more importantly—it was about people. At Einfratech Systems, we love a well-structured function as much as the next dev team.

Ever joined a GitHub Enterprise and thought, “Who organized this… chaos?” I created this post because in the last few months I always got the same questions from customers about how they could structure GitHub Enterprise, especially something like: “How many organizations I need to create?” GitHub Enterprise is incredibly powerful — but only if it's structured right. As your engineering org grows, so does your sprawl: multiple organizations, dozens (or hundreds) of repositories, unclear team access, and policies all over the place. The result? Confusion, security gaps, and onboarding pain for every new dev. I’ve seen GitHub Enterprise setups ranging from tightly governed to wild west mode, and the difference usually comes down to one thing: how well the org is structured. This post is base…  ( 6 min )

NEWSARC.io: A New Way to See the World — Perspective on a Timeline Introduction: Have you ever felt like you’re only seeing part of the story? Imagine standing in a room with just one tiny window. Every day, you look through it and see the same view. It becomes familiar — comforting, even — but deep down, you know there’s more out there. That’s how reading the news often feels for me. While trying to understand global events — wars, politics, markets, climate crises — I kept hitting the same wall: limited perspectives, missing context, and headlines that seemed to nudge me toward a conclusion rather than help me form one myself. I didn’t want pre-packaged opinions. I wanted the full picture and to be able to research myself. As a developer (and, let’s be honest, a bit of a news junkie r…  ( 5 min )

What is Recursion? Recursion is when a function calls itself to solve smaller parts of a problem — ideal for tasks that can be broken down into repetitive subproblems. ✅ Basic Recursive Structure def function_name(): # base condition if condition: return something else: return function_name() # recursive call Without a base condition, the function will keep calling itself forever — causing a RecursionError. 💡 Example 1: Factorial Using Recursion def factorial(n): if n == 0 or n == 1: # base case return 1 else: return n * factorial(n - 1) print(factorial(5)) # Output: 120 Here’s how it works: factorial(5) → 5 * factorial(4) → 5 * 4 * factorial(3) → 5 * 4 * 3 * factorial(2) → ... → 5 * 4 * 3 * 2 * 1 = 120 💡 Example 2: Fibonacci Series Using Recursion def fibonacci(n): if n == 0: return 0 elif n == 1: return 1 else: return fibonacci(n-1) + fibonacci(n-2) for i in range(7): print(fibonacci(i), end=' ') # Output: 0 1 1 2 3 5 8 🔨 Mini Project: Factorial & Fibonacci Calculator def factorial(n): return 1 if n <= 1 else n * factorial(n - 1) def fibonacci(n): if n <= 1: return n else: return fibonacci(n - 1) + fibonacci(n - 2) num = int(input("Enter a number: ")) print("Factorial:", factorial(num)) print("Fibonacci:", fibonacci(num))  ( 3 min )

A website passes an automated accessibility scan with flying colors. The dashboard shows zero errors, and you're feeling confident. But when a screen reader user attempts to navigate the site-or someone tries to operate it with a keyboard only-the experience falls apart. Automated accessibility testing tools are useful, no doubt. They speed up checks, catch many critical issues, and help enforce web standards like WCAG. But they’re not infallible. Many nuanced and contextual issues fly under the radar, and relying on automation alone can give a false sense of compliance. To build truly inclusive digital experiences, human insight is essential.

Hey folks! TL;DR: Rive is a big deal for designers, and developers. I've been experimenting with motion design & micro interactions lately. As context, I'm a full stack dev with a background in design & motion. I've always dreamed about a way to make animations in After Effects that are NOT just meant to be exported as .mp4 files but actual interactive animations I could use on my websites or apps. Back in the day, I messed around with Lottie using the Bodymovin plugin for After Effets in order to achieve that. I'm not gonna lie: it "worked" but it was very bad DX and not really efficient (big JSON animation file). -- 5 years later -- I stumbled upon Rive and started to experiment with it, and wow it's exactly what I would dream about: An animation tool that can export lightweight and interactive animations with full control through code. The export is a .riv binary file that is loaded by the Rive SDK. Starting from that, you can interact with your data bindings and inputs set in Rive in plain JS, enabling infinite possibilities! My personal take is that with the incoming flood of average software due to AI, design delight will be back. And this Rive thing is probably a big deal for the future. Let me know your thoughts!

One of the recurring issues many companies face is the struggle to optimize their financial systems. Delayed transactions and complex integrations often happen because there’s no real-time data coming in from customers. In most cases, this is due to financial information being locked away in separate systems. On top of that, customers expect smooth and seamless transactions, even as their needs continue to change. This growing demand creates more pressure on businesses to keep up. To resolve these challenges, open banking was introduced. It's a model that gives integrators more control over financial data, making it easier for businesses to deliver fast, secure, and personalized financial experiences. And it’s not just for financial service providers. Traditional companies can also tap int…  ( 9 min )

For instance, the ENIAC had a memory capacity of about 20 words, each 10 decimal digits long, and operated at a clock speed of 100 kHz. These limitations necessitated a meticulous approach to software development, where every byte and clock cycle counted. Developers often wrote programs directly in machine code or assembly language to maximize efficiency. Machine code consists of binary instructions specific to the hardware, while assembly language uses mnemonics to represent these instructions. Both approaches allowed for precise control over hardware resources. For e…  ( 5 min )

Most developers are still building apps like it’s 2015. Jumping between Figma, Notion, Bubble, and ChatGPT. More hours. More tabs. More burnout. But in 2025, the smartest builders are taking a different path. They don’t hire teams. They hire one smart AI that works like a partner. From Code Monkey to Creative Director You wouldn’t hire a full-stack dev, a content strategist, a UX writer, and a project manager just to ship an MVP. You’d go broke before launching. So what if you could think like a founder — but execute like a team of 5, using one AI assistant that gets it? Welcome to the new model: What This Looks Like in Practice Visualize the Entire App in Minutes With [Chart Maker], I sketched the user flow with a simple prompt: “Create a flowchart for a social journaling app with streaks…  ( 4 min )

I used to have a tool for everything. One for debugging. The more tools I added, the more fragmented my workflow became. I wasn’t developing faster. That’s when I realized… I didn’t need more tools. I needed one smart assistant that thinks like a dev. The Developer’s Bottleneck Isn’t Code — It’s Context Switching You Google a Stack Overflow answer Bounce into VS Code Copy from ChatGPT Jump to Notion or Slack Rewrite the same function three times You’re not slow because you don’t know what to do. Enter: My AI Dev Stack (Without the Stack) Here’s what changed: One prompt replaces 5 tools I debug code, write docs, generate UI, and brainstorm systems — in one place It remembers my logic Crompt stores my dev patterns, past code snippets, and naming conventions so I never start from scratch It thinks in systems, not snippets Most AI gives you one-off answers. Crompt builds with you like a co-pilot who’s in sync with your style and stack Real-World Use Cases I Run Daily Write and optimize backend functions for async workflows Translate pseudocode into clean, production-level syntax Audit entire code blocks for bugs and performance Explain complex logic in plain English (great for team onboarding) Auto-generate documentation based on real code context The Hidden Benefit: Focus One platform means fewer tabs, fewer decisions, and more uninterrupted flow. I now spend more time solving real problems — and less time stitching my workflow together. No more prompt recycling. Developers Don’t Need More Power. They Need More Leverage. It’s here to: Accelerate the thinking process Protect your mental energy Build systems that scale with your growth That’s what Crompt AI does. It’s not a chatbot with code wrappers. Try the Stack That Replaces Your Stack Start building with one platform that evolves with you. Crompt AI is the all-in-one AI assistant that helps you think, code, ship, and optimize — like a founder-engineer, not a task-runner. Replace the clutter. Crompt is the dev stack without the stack.  ( 4 min )

A stakeholder comes to your desk. They're excited. "We need to use AI," they say, "to improve customer retention." You nod, open your editor, and you start thinking. Should I use XGBoost? Or maybe a neural network? How will I set up the pipeline? Stop. Right there. This is the single biggest mistake many of us make when we're starting out: we jump straight to thinking about solutions and algorithms. We're so excited to play with the cool, technical thing that we forget to ask the most important question first: What problem are we actually trying to solve? The most valuable skill for a data scientist isn't knowing every algorithm under the sun. It's easy, Google has ton of code to help with that, LLMs can help out too.

Skip the Storage Fees - A Weekend Project Hey folks — if you’ve ever hit that dreaded “iCloud storage full” alert and groaned at paying Apple even more money, you’re definitely not alone. I was in the exact same boat. My iCloud Photos library was eating up gigabytes like candy, and I needed a way to offload originals somewhere safe without losing my carefully organized albums. So I figured — why not automate the whole thing AND keep my album structure intact? I personally LOVE having photo albums, keeps them together labelled with the moment! Here’s how I ended up building a smarter macOS app using Automator, AppleScript, and a pinch of Python. This thing backs up all my full-resolution iCloud Photos with their album organization from my Mac to an external SSD with just a click. No third…  ( 9 min )

Imagine your toy box. You have one in your room. Your brother has one in his room. You can't reach into his toy box, and he can't reach into yours. That's scope. Now, let’s say your toy robot remembers your name even when you leave the room. That’s closure. Let’s go a bit deeper (but still like you're 5): Scope means "who can see what." function playRoom() { let toy = "robot"; console.log(toy); // ✅ can see robot } console.log(toy); // ❌ error, can't see robot Why error? Because toy is in the playRoom. Outside can't see inside. Closure means a function remembers things from where it was born. function makeToy() { let toyName = "Buzz"; return function() { console.log("Playing with " + toyName); }; } let play = makeToy(); play(); // ✅ "Playing with Buzz" Even though makeToy() is done, the inside function remembers toyName. That’s a closure. Scope: "You can only use your toys in your room." Closure: "You made a magic toy that remembers your name, even if you take it outside." Helps avoid bugs. Lets us write smart code like hiding secrets or making factories. Used in React hooks, event handlers, and more. Scope = "Where can I see this?" Closure = "I remember where I came from." Want to test it? Try these: // Challenge 1 function box() { let secret = "shhh"; return function() { console.log(secret); } } box()(); // What will it print? // Challenge 2 let a = 10; function outer() { let a = 20; function inner() { console.log(a); } return inner; } let result = outer(); result(); // Guess the output! Keep playing with the code. Think of scopes as rooms and closures as memory toys. Happy coding like a 5-year-old genius! 🎉  ( 3 min )

Hi all! Today I continued learning about the video element and all its attributes. We need an attribute called controls enabled in order for the video to play....also we need to mention the type of video format so that the browser can render it accordingly. We can also give attributes like autoplay muted and loop to the source tag so the the video plays automatically each time the website is loaded. But some users might find autoplay as a form of violation of their privacy and so we must try and avoid using autoplay. Youtube video in the website. This can be done using the iframe tag and the url can be obtained by selecting the share option in the desired Youtube video and copying the code given under embed tab into the iframe. Similar to regular video we can also use autoplay and mute options in this. However these should not be written as seperate attributes but should be written at the end of the iframe URL address with their values set to 1. So that's all for today.....see you all in the next post!  ( 3 min )

From Tool Chaos to Development Zen: A Developer's Journey to the Perfect Workflow Kruti for Teamcamp ・ Jun 16  ( 2 min )

Recent research has cast new light on the limitations of modern AI “reasoning” models. Apple’s 2025 paper The Illusion of Thinking shows that today’s Large Reasoning Models (LRMs) — LLMs that generate chain-of-thought or “thinking” steps — often fail on complex problems. In controlled puzzle experiments, frontier LRMs exhibited a complete accuracy collapse beyond a complexity threshold. In other words, after a certain level of difficulty, their answers become no better than random. Equally striking is their counter-intuitive effort scaling: LRMs ramp up their chain-of-thought as a problem grows harder, but only up to a point. Beyond that, they actually give up — even when the token budget remains ample, their detailed reasoning steps abruptly shrink. These findings suggest a fundamental ga…  ( 8 min )

Welcome to Day 9 of our FastAPI Zero to Hero series! Today we unlock one of the most powerful (yet misunderstood) tools in modern web development — Async Programming. Writing non-blocking code can be accomplished through async programming. This implies that your program doesn't wait for sluggish operations (such as file reads or API requests) to complete before continuing. Alternatively, it can work on other projects in the background when those tasks finish. You're cooking dinner 🍳 and waiting for the rice to boil. While it boils, do you just stare at the pot? Nope — you chop veggies or scroll through Instagram reels. That’s asynchronous behavior — you’re multitasking efficiently. Async is the engine behind that speed and FastAPI is built for speed. When a route is defined with async de…  ( 6 min )

Today, I made good progress in learning React by exploring some very important concepts: useState, the spread operator (...), and the map() function. These features are essential for building dynamic and interactive components in React. Below, I’ll share what I learned with simple explanations and examples. useState Hook – Managing State in Functional Components In React, state is used to store data that can change over time. The useState hook helps us add state to functional components. const [state, setState] = useState(initialValue); import React, { useState } from 'react'; function Counter() { const [count, setCount] = useState(0); return ( Count: {count} setCount(count + 1)}>Increase ( {fruit} ). The key is used to uniquely identify each element.  ( 3 min )

Table of Contents Introduction Understanding the as const keyword Conclusion In Typescript, type inference is powerful, but sometimes we need more control over the types in our code. This is where the as const keyword comes in. By using as const, we ensure that Typescript treats our values with specific types, preserving and using their exact value instead of generalising them. In this article, we'll explore how the as const keyword works and how it can enhance your development with Typescript Typescript uses broader types when inferring the type of a value. For example, when you declare a variable with a string, Typescript will infer the type as string, rather than the exact string value you assigned. However, using the as const, you are telling Typescript to treat the value as a con…  ( 5 min )

“It’s just S3. What could go wrong?” If you’ve ever had this thought while deploying an app, building a static site, storing user uploads, or integrating backups, you're not alone. But you might also be unknowingly misusing one of the most powerful — and deceptively simple — services in the AWS ecosystem: Amazon S3 (Simple Storage Service). Yes, S3 — the Swiss Army knife of AWS. It sounds harmless, even elegant: a “bucket” where you store your files. But the truth is, most developers (up to 85%) are not using S3 the right way, especially at scale or in production-grade applications. From skyrocketing costs, broken performance, misconfigured security, to compliance nightmares — the misuse of S3 creates hidden dangers that quietly eat away at your infrastructure. The beauty and danger of S3 …  ( 7 min )

A junior developer's guide to understanding component execution strategies If you're just starting your frontend journey, you've probably heard terms like "compilation," "build process," and "bundling" thrown around.

AWS recently announced something awesome: CodeBuild now supports remote Docker servers! 🎉 But wait... what does that even mean? Let me explain with a simple example that anyone can follow 👇 Every time you cook pasta, you do the same steps: Boil water 🍲 Cut vegetables 🥕 Make the same sauce 🍅 Cook pasta 🍝 Now imagine doing this from scratch every single time — even if the recipe doesn't change! 😩 Wouldn't it be smarter if your kitchen assistant saved your sauce, chopped veggies, and hot water, so you could reuse them and cook faster? Before Every time AWS CodeBuild ran a Docker build, it started from zero. It downloaded everything again (base image, node modules, etc.) ⏳ Builds were slow, even for tiny changes. Now AWS provides a remote, invisible Docker server just for you. This server remembers your past Docker layers (cached!). Next time you build — it’s faster, because it reuses what didn’t change. 🚀 Your Dockerfile for a Node.js app: FROM node:20 COPY package.json . RUN npm install COPY . . CMD ["npm", "start"] First Build All steps run from scratch. ⏱️ Next Build Docker skips node:20 (already cached) Skips npm install (if package.json didn’t change) ✅ Only rebuilds what actually changed! Without Remote Server With Remote Server Always builds from scratch ❌ Reuses cached layers ✅ Slower CI/CD ⏳ Faster builds 🚀 More compute & network usage 💸 Efficient + cheaper 💡 Nope! 🎉 This feature is a game-changer for developers using AWS CodeBuild and Docker. Let AWS handle the caching magic while you focus on building cool stuff! 🔥 Let me know in the comments if you've tried this — or if you want help optimizing your Docker builds on AWS! 💬  ( 3 min )

What if the real test isn't your code but your restraint? It's about patience. This isn't just a dev post. It's a reminder that clarity always outlasts cleverness. Premature optimization isn't just a technical misstep. It's a temptation to perform instead of serve. If you build with care, write for others, and believe code should hold over time, this one's for you. Read: The Cost of Premature Optimization: Discipline Before Cleverness  ( 3 min )

En la integración de sistemas, es común tener que consultar grandes volúmenes de información a servicios externos que tienen límites estrictos o, simplemente, servicios de terceros donde no tenemos la posibilidad de solicitar un escalamiento. En los últimos años, he tenido la "oportunidad" de desarrollar soluciones para migraciones de datos con volúmenes entre 1.000 y 300.000 registros, con datos que dependen de otros sistemas, en su mayoría legacy. Si a eso le sumamos que muchos de estos no podían ser escalados para soportar consultas muy grandes porque colapsaban, la situación se volvía un dolor de cabeza. Y dado que no era viable una solución trivial como hacer llamadas individuales para cada elemento porque eso no es eficiente, es costoso y poco sostenible , necesitaba una forma simple…  ( 5 min )

Author: Andrei Leonov Introduction What if an AI could discover physical laws — not by being told the answer, but by evolving its own formulas? What if the result looked like pure nonsense — yet hid a physically perfect structure underneath? This is the story of a formula that is at once absurd and brilliant. Generated by symbolic regression using genetic programming (GP), the expression appeared chaotic and unreadable. But after careful analysis, it revealed a deep, interpretable pattern — one that could be used in physics, geometry, and even memory modeling in AI systems. The Raw Formula (a Monster) X′ = neg(((tanh(x) / pi) * (1 + p1))) The formula was one of many evolved by a symbolic GP system trained only to minimize MSE — no physics was built in. At first glance: complete chaos. Deep…  ( 4 min )

LeetCode 3405 | Hard | Combinatorics You are given three integers: n: length of the array m: range of values [1, m] k: number of adjacent equal pairs You must find the total number of "good arrays", where: Every element lies in the range [1, m] Exactly k indices i (where 1 ≤ i < n) satisfy arr[i - 1] == arr[i] Since the result may be large, return the count modulo 10⁹ + 7. To construct a valid array: Pick k positions (from the n - 1 possible adjacent pairs) to be equal. The first element can be any value from 1 to m. For each of the n - 1 - k remaining positions (which must differ from the previous element), there are m - 1 options. So, the total number of such arrays is: C(n - 1, k) × m × (m - 1)^(n - 1 - k) Where: C(n - 1, k) is the number of ways to choose k adjacent positions to…  ( 5 min )

Building modern search experiences shouldn't be rocket science. Let me show you how to create a blazing-fast, real-time search system using TypeScript, Hono, and React. Ever tried implementing search functionality and ended up with a sluggish, overcomplicated mess? You're not alone. Most developers either: Over-engineer with complex search engines like Elasticsearch Under-deliver with basic string matching that feels broken Get lost in the complexity of fuzzy search algorithms What if I told you there's a sweet spot? A TypeScript-first solution that's both powerful and simple? search-plus-ts is a lightweight, TypeScript-native search library that brings intelligent search capabilities without the overhead. Today, I'll walk you through building a complete full-stack search application using…  ( 6 min )

This section demonstrates the features and usage of the new Indicator navigation point component in HarmonyOS API 15. DevEco Studio 5.0.5 Release The Indicator navigation point component offers two styles of navigation points: dot navigation points and digit navigation points. This component has been supported since API Version 15. It provides the existing capabilities of the Indicator in the original Swiper component as a standalone component for developers to use. Developers can display navigation points independently without relying on the Swiper component, or they can bind it with the Swiper component using the IndicatorComponentController. When multiple navigation point components are bound to the same Swiper component, only the last navigation point component will successfully bind t…  ( 6 min )

Presented at DevFest 2024, Johannesburg Artificial Intelligence is no longer the exclusive domain of massive corporations or high-end research labs. With the rise of open-source models like Gemma and modular frameworks like LangChain, it is now possible to build robust, domain-specific AI systems using publicly available tools. At DevFest Johannesburg 2024, I walked through how to build a Retrieval-Augmented Generation (RAG) system using Gemma, LangChain, and Vertex AI — with a working chatbot demo and live deployment. RAG is an AI architecture that combines: Information retrieval (search, databases, document indexes) Generative language models (like Gemma or Gemini) This enables systems to access external knowledge, retrieve relevant content, and use that content to ground the generation …  ( 5 min )

What is a Hook? Hooks allow function components to have access to state and other React features. Because of this, class components are generally no longer needed. Hooks allow us to "hook" into React features such as state and lifecycle methods. Why used Hooks? Although Hooks generally replace class components, there are no plans to remove classes from React. Hook Rules** There are 3 rules for hooks: Hooks can only be called inside React function components. Note: Hooks will not work in React class components. useState in React React's useState hook lets you add state to functional components. import { useState } from 'react'; function Counter() { return ( Count: {count} An array is a list-like object used to store multiple values in a single variable. const fruits = ['apple', 'banana', 'cherry']; Arrays can hold any data type — strings, numbers, objects, or even other arrays. The Spread Operator (...) The spread operator allows you to quickly copy or merge arrays and objects. const original = [1, 2, 3]; console.log(copy); // [1, 2, 3] Adding elements: const numbers = [1, 2, 3]; console.log(moreNumbers); // [1, 2, 3, 4, 5] Merging arrays: const a = [1, 2]; console.log(combined); // [1, 2, 3, 4] Using map() to Transform Arrays The map() method lets you apply a function to every element in an array and returns a new array. const numbers = [1, 2, 3]; console.log(doubled); // [2, 4, 6] In React, map() is commonly used to render lists of components: const items = ['pen', 'notebook', 'eraser']; return ( {item} )} );  ( 3 min )

"Your database is fighting itself—and the reads are winning." In most Rails apps, the same ActiveRecord model handles: Writes (validations, callbacks, transactions) Reads (API responses, dashboards, exports) But when traffic grows, this becomes a zero-sum game: Heavy reporting queries slow down writes Write locks block frontend reads Schema changes risk breaking both paths Command Query Responsibility Segregation (CQRS) decouples reads from writes—letting you scale them independently. Here’s how to implement it without leaving Rails behind. 1. CQRS in 60 Seconds Traditional Rails # User model does everything class User < ApplicationRecord def activate! update!(active: true) # Write end def self.active_users where(active: true) # Read end end CQRS Ra…  ( 4 min )

What is Blockchain? Blockchain is a decentralized, permanent digital ledger that records transactions across many computers. This setup makes it nearly impossible to change past records. Instead of relying on a central authority (like a bank), blockchain promotes transparency, security, and efficiency by sharing control among participants. Transactions are grouped into blocks, and each block links to the previous one, creating a chain. These blocks are protected using cryptography, ensuring the data inside can’t be altered once added. A blockchain runs on a peer-to-peer network. When a transaction happens: It is broadcast to many computers (called nodes). The nodes verify the transaction through consensus methods like Proof of Work (PoW) or Proof of Stake (PoS). Verified transactions are…  ( 5 min )

As a student developer who is exploring AWS technologies, I recently came across Amazon Q and its current event. The event encouraged participants to build a game, and that instantly hit a nostalgic chord in me. A few years ago, I've created a simple game in Unity without knowing how to code. Now, equipped with two years of coding experience and the help of Amazon Q, I managed to recreate that idea as a full parody arcade game using pygame-ce in just one day! Although AI tools are not new to me and to everybody, it still amazes me how much faster development becomes with the use of it. So in this short post, I’ll be sharing a quick look at how Amazon Q helped me bring this fun small project to life. The game is called the "The Last Bluebook".

This is the third release of Pulumi Gestalt, a universal runtime for Pulumi. Pulumi schemas have traditionally been stored in YAML files, but the complexity of their content often leads to a lot of boilerplate when mapping into domain objects. In Pulumi Gestalt 0.0.3, both the Rust and C FFI targets (Wasm coming later) now support obtaining schemas as native Rust structs or serialized Protobuf messages for C. The Protobuf schema is designed to be straightforward—no additional mapping logic required. Check documentation for more info: https://pulumi-gestalt.readthedocs.io/v0.0.3/integrations/overview/#get-schema https://pulumi-gestalt.readthedocs.io/v0.0.3/integrations/schema/ Give Pulumi Gestalt 0.0.3 a try and let me know what you think!  ( 3 min )
